Re^2: Maintaining context of the caller

That's not so great. If scalar context is going to be used, then you're using unnecessarilly wasteful operations. Store the result in a scalar and return the scalar. Don't store into an array, construct a list of indexes, and return a list slice.

Then again, I'm just against wasting resources on something so trivial. I write my code to call wantarray() multiple times because I know that's cheaper (it should be, anyway) than dealing with all that listy business.

The aesthetical "correctness" of code will vary depending on one's point of view, but I think your concerns stem more from my question than ikegami's answer. I asked for a way to avoid duplicating the context-checking logic, and he provided it. I happen to think his is a very nice solution, but of course reasonable folks can disagree.	[reply]
