What was the output of your test script
Hello,
$s="hello,test";
the 1st statement:
$s=~s/^(\w+)/$1 /
the 2nd statement:
$s=~s/^(\w+)/\1 /
What's the difference between these two statements?
Thanks!

Probably. Imports are package-scoped. Now you're working in package

Hi,
Following on from the earlier thread about storing common code in a
central file, I have hit a problem when trying to do something
similar.
I have been toying with SOAP. There seems to be a number of ways to
create SOAP services and I opted for one of the examples at
guide.soaplite.com.
So it sounds like from what you're saying, maybe the structure is a
double-linked list? That would give the behaviour you're talking about.

Here is the benchmark I used. You can play around with $k (the

Whoops, make that $mid rather than $k.

Yes,'1' is needed.When you requie a file in a perl script but that file return

Hi,
Hi,
I want to set pathnames in a centralised module (called with use or
require). Is it possible to send an variable (through the env or as an
argument, or ) so I can use the variable $dir from the module
test.pl to set the variable $vardir in param.pl. ??
Any help greatly appreciat

There are border cases though:
perl -Mstrict -MData::Dumper -wle'
$_ = { AB => 1, +AB => 2, -AB => 3 }
