Yes it's possible, reading Simon Cozens' Advanced Perl, I found this whitch work:

foreach my $f (@files) {
    my $config = Config::YAML::Tiny->new( config => $f );
    my @template_file = split( / /, $config->get_template );
    foreach my $tf (@template_file) {
        my @fields = split( / /, $config->get_fields );
        for my $v ( @fields ) {
            no strict 'refs';
           
             *{"T::$v"}= \$config->{$v};
        
        }
        my $template = Text::Template->new(
            TYPE   => 'FILE',
            SOURCE => $tf

        ) or die "Couldn't construct template: $Text::Template::ERROR"
+;

        my $result = $template->fill_in(  
            PACKAGE => 'T',
            PREPEND => 'use strict;'
           );

And in the template file(s) I had to change $value with $T::value, $pos with $T::pos

update In fact, with $T::pos in the template file, I loose the error if the variable name is wrong: $T:ops is just replace by nothing but no error is given. I have to use $pos or $value in the template.

The docs could be made clearer I think
