in thread Checking number of values returned

Well now you make me think about it, I suppose that I do habitually assign my functions to individual scalars. Perhaps this is the XY problem referred to earlier but actually I find that doing it this way makes my code much more understandable so would argue that it's a good thing. Anyway, even if I only did it only 30% of the time, it would still seems to be a valid useful thing to check for those 30% that were checkable...

    It sounds like the XY problem is that you've come to Perl from another language and haven't yet fully made the transition.

    I have the reverse problem. Every time I use C; I find my self wishing I could return multiple -- and variable numbers of -- values from functions:)

    And the funny thing is that if you always assigned your results to an array, it would be much easier to check the number of returned values:

    my @results = someFunc(); die unless @results == 3; ...

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

    In the absence of evidence, opinion is indistinguishable from prejudice. Agile (and TDD) debunked
