Second the motion. In fact, Last night I spent a little time writing a
rebuttal, but then I tried it, and you're exactly right. I figured this
would be the last word, but should have known better.
In support of the correct position:
C:\>perldoc -f wantarray
wantarray
Returns true if the context of the currently executing
subroutine is looking for a list value. Returns false if the
context is looking for a scalar. Returns the undefined value if
the context is looking for no value (void context).
return unless defined wantarray; # don't bother doing more
my @a = complex_calculation();
return wantarray ? @a : "@a";
This function should have been named wantlist() instead.
