Re^2: Mini-Tutorial: Scalar vs List Assignment Operator
in thread Mini-Tutorial: Scalar vs List Assignment Operator
On "preventing a function that returns a scalar from being called in list context".. yes, I agree. I did say that it probably wasn't a good idea. The idea was just to show how to use wantarray: ie, how to test the various return values.
I had a suspicion as well when I wrote the code that the syswrite wasn't correct. Thanks for pointing it out.
With all that was wrong with my post, don't I at least get some credit for suggesting that programmers should test the return value of syswrite instead of assuming it works? Besides flagging that wantarray could be useful here (if only so the programmer has a way to test directly whether a particular construct implies a list or array context) that's the other point I was trying to make.
