Re: calling sub and returning value from the same line

in reply to calling sub and returning value from the same line

How about this, instead?

sub error
{
    warn map { "$_\n" } @_;
    return undef;
}

#
# and later
# 

open FH, ">$_[0]" or 
    return error($!, "not able to write to file $_[0]");

`return`; is almost always preferable to `return undef;`.	[reply] [d/l] [select]
