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.]
