Syntax checking - or how to lose against a >
I wasted way too much time debugging a silly syntax error.
To make a long story short, here’s an equivalent of what I was writing:
my $foo => Some::Class->new; say defined($foo) ? 'foo is defined' ! 'foo is NOT defined';
Easy to spot now that you know that there’s something fishy around, uh?
If you didn’t spot it already, there’s a stray
> character that totally
changes the meaning of the
= sign immediately before, thwarting the
$foo remains unassigned and
I could only figure out this after writing a brand new line like the following, and putting it close to the original
my $bar = Some::Class->new; my $foo => Some::Class->new;
Of course now, with the right alignment and puntuation, the solution appears trivial. Now being the key concept.
Stay safe and keep both eyes open!
