Re^2: curly braces inside of curly braces

Nested paired delimiters also work:

c:\@Work\Perl>perl
use strict;
use warnings;

my %test_hash = ("foo_bar" => "baz");
my $test = "foo";

my $var5 = qq{aaa/$test_hash{ qq{${test}_bar} }};  # qq{} in qq{}
print "var5 = '$var5' \n";
^Z
var5 = 'aaa/baz'

I agree a surfeit of curlies or any other delimiter can cause visual indigestion, but I wanted to use as many as possible to drive the point home in the example. :) Update: Oops... I meant this to be a reply to LanX's post. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]

Yeah true, their delimiters can be nested, but I'd chose other one(s) to avoid being distracted by other curlies like in `${test}` `qq(aaa/$test_hash{ qq(${test}_bar) });` and readability is why I kept " in the first place `qq(aaa/$test_hash{ "${test}_bar" });` Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]
