Re: perl bug with references


Quoth "dt" <ppc@xxxxxxxxxxxxxx>:
I found an odd behavior.

when I have a reference, let's say it is an array, it seems to pad the
value differently in perl 5.6 vs 5.8:

this worked in perl 5.8 but not perl 5.6:

$ref =~ /^ARRAY/;

for 5.6, I had to change to =~ /^\s*ARRAY/;

could not find anything mentioning this behavior anywhere. I doubt it
is a "feature"

Works for me:

~% perl -v

This is perl, v5.8.8 built for i686-linux
....

~% perl -le'print [] =~ /^ARRAY/ ? "match" : "no match"'
match
~%

You shouldn't be doing this anyway. Use Scalar::Util::reftype.
