== Task clarification ==
I would think the intent would be to show that strings can be manipulated within the language. At least one example shows what appears to be print formatting only. I would think that that wouldn't meet the intent. So a printf would not pass but an sprintf would.
:Yes, but, has it gone too far to correct? --[[User:Paddy3118|Paddy3118]] 07:03, 1 June 2010 (UTC) :: It isn't going to get any better. Another (less widespread) problem is documentation. Fixing it, will just have to look ugly for a while with all the attention tags. The problem is the Wikipedia article shows printf for variable interpolation which is referenced. Choices: ::# Let it ride (and maybe make it clear it's okay) ::# Clarify and make keeping the result in a string a requirement. Then flag. ::# Clarify and make it optional to show that the interpolated string can be retained in the program for further manipulation. Then (optional or different) flag? Or not? :: Thoughts? --[[User:Dgamey|Dgamey]] 11:26, 1 June 2010 (UTC) ::: I'm in favor of option 3, combined with consideration of another; correct the code example on Wikipedia's talk page in a way that won't raise the ire of the page's protector. --[[User:Short Circuit|Michael Mol]] 15:48, 1 June 2010 (UTC) :::: I like that approach. -[[User:Dgamey|Dgamey]]

:There seems to be another problem with this task, as I see it:
In traditional interpolation characters and variables are represented by a notation within the string, but I notice that some solutions are calling a substitution routine from within the language. This is really "substitution", rather than "interpolation". Iterpolation is implicit, whereas substitution is explicit (blimey that probably sounds more confusing - huh). Maybe the following examples clarify.
- "Mary had a $type lamb." # This is interpolation (not substitution)
- replace "type" with "little" in the string "Mary had a type lamb" # This is substitution (not interpolation)
Also what does the (included) bit mean in the task title?
I suggest we knock this task back to draft and sort out the description.

:It seems to me that ''most'' solutions perform substitution instead of interpolation. Maybe this is because the task description is quite unclear. Also, the term "interpolation" is quite misleading. I did not understand the task until I read the Wikipedia article. --[[User:PauliKL|PauliKL]] ([[User talk:PauliKL|talk]]) 14:48, 3 July 2013 (UTC)
There is already some discussion on WP
- [http://en.wikipedia.org/wiki/String_literal#Variable_interpolation] reference page is not the main article
- [http://en.wikipedia.org/wiki/Variable_interpolation] main article The talk pages already cover some of this.
- [http://en.wikipedia.org/wiki/Talk:Variable_%28programming%29] (the first jump with little on it of relevance)
As far back as 2006, the fact the printf wasn't needed. Yet the examples seem a bit of a mix mash. -[[User:Dgamey|Dgamey]]
