Generally, backwards compatibility with the Bourne shell is of course a valuable asset nowadays. But wouldn't it be better to go the whole distance? The Bourne-shell was built as an extension to the Thompson-shell (osh) in which the backticks won't work either. To avoid backwards compatibility problems with systems lacking a Bourne-shell and having only a Thompson-shell (like, for instance, most pre-SysV-systems as well as perhaps all the Multics systems) maybe a completely different approach would be best?

Actually it works in any ksh, not only ksh93. In fact this is exactly what i said:

Does the same in ksh and bash
I still have to see a "POSIX shell" which is not either a "POSIX-compatible ksh" or a "POSIX-compatible bash", therefore i think that the POSIX-issue is moot in this case.

I hope this helps.

Catalyst::Helper::HTML::FormFu(3pm)			User Contributed Perl Documentation		       Catalyst::Helper::HTML::FormFu(3pm)

NAME

       Catalyst::Helper::HTML::FormFu - Helper to deploy HTML::FormFu template files.

SYNOPSIS

	   script/myapp_create.pl HTML::FormFu

DESCRIPTION

       As of version 0.02000, HTML::FormFu doesn't use the TT template files by default - it uses in internal rendering engine.

       If you don't want to customise the generated markup, you don't need to use Catalyst::Helper::HTML::FormFu at all.

       If you want to customise the generated markup, you'll need a local copy of the template files. To create the files in the default
       "root/formfu" directory, run:

	   script/myapp_create.pl HTML::FormFu

       To create the files in a different subdirectory of "root", pass the path as an argument. The following example would create the template
       files into the directory "root/forms".

	   script/myapp_create.pl HTML::FormFu forms

       You'll  also need to tell HTML::FormFu to use the TT renderer, this can be achieved with Catalyst::Controller::HTML::FormFu, with the
       following Catalyst application YAML config:

	   ---
	   'Controller::HTML::FormFu':
	     constructor:
	       render_method: tt
