in reply to embedding a scalar into a string without space after the scalar

Gulliver,

I'm not sure this directly answers your question, but it does show another way to accomplish what I think you are trying to do:

#!/usr/bin/perl use strict; use warnings; use Data::Dumper; my $tmp ='./tmp/'; my $filename_template = '%sfile%02d.zip'; my @zips = map { sprintf $filename_template, $tmp, $_ } (1 .. 5); print Dumper(\@zips);
__OUTPUT__ $VAR1 = [ './tmp/file01.zip', './tmp/file02.zip', './tmp/file03.zip', './tmp/file04.zip', './tmp/file05.zip' ];
I don't think it's a good idea to store the scalar in the string. Much better to provide a means to generate the name programmatically, IMHO.

[1nickt]: \my %foo = { bar => 1 }; say $foo{bar};
[Corion]: 1nickt: Would be great, especially for naming parameters in @_.
[Corion]: When you pass an arrayref, you get to treat it like a local array. But then, I'm cautious with the experimental features, because just when I thought function signatures were a set thing, there is a proposal to use sub [ $foo, $bar ] { ... } to ...
[Corion]: ... declare the parameters, instead of the more common sub ($foo, $bar) { ... }
