Re: Create string with a delay

This is easy. Use Data::Postponed. I wrote this module to handle just this kind of task.

use Data::Postponed 'postpone_forever';

$a = '';
$str = postpone_forever( "blabla" . $a . "blabla" );
$a = "XXX";
print "$str\n"; # prints blablaXXXblabla

[Edit. I originally goofed by using $x instead of $a. Sorry. That typo is gone now. I also made the string "$blabla${a}blala" nicer to read.]

Surely, that module isn't capable of reversing the concatenation of its arguments, and then performing it again, is it? Perhaps you meant something more like this: `$a = ''; $str = "blabla" . postpone_forever( $a ) . "blabla"; $a = "XXX"; print "$str\n";` [download]	[reply] [d/l]

Oh, yeah, you're right. `$a = postpone_forever( '' )` would have been ok as well as `$str = postpone_forever( "blabla" ); $str .= $a; $str .= "blabla";`. Anything like that would be ok. ⠤⠤ ⠙⠊⠕⠞⠁⠇⠑⠧⠊	[reply] [d/l] [select]
