There is a bug in Template -- ok, supposidly this is actually a bug in perl, but I am sure that the author of Template could have worked around the issue. Basically, you cannot use the 'Interpolate' feature of the module when loading a template larger than ~30k; if you do, perl will dump core, segfault, or do something of the sort.

Here's the example that I have in which Template fails: 

my $TMPL = Template->new( {
    DELIMITER    => ';',
    INCLUDE_PATH => 'C:/Apache2/sites/foobar/template',

    INTERPOLATE  => 1
} );

$TMPL->process( \*DATA, {
    screen => qw(screen1 screen2)[rand 2]
} );

__END__
[% INCLUDE primary/html_head.tmpl %]
[% INCLUDE "$screen" %]
[% INCLUDE primary/html_foot.tmpl %]

[% BLOCK screen1 %]
This is screen #1.
[% END %]

[% BLOCK screen2 %]
This is screen #2.
[% END %]

Of course, it is possible to work around this in this fashion: 

__END__
[% INCLUDE primary/html_head.tmpl %]

[% IF screen == 'screen1' %]
    [% INCLUDE screen1 %]
[% ELSIF screen == 'screen2' %]
    [% INCLUDE screen2 %]
[% END %]

[% INCLUDE primary/html_foot.tmpl %]

[download]

But if I have several screens, this can get very annoying to code and is definitely ugly. Can anybody think of a way to get around this alternative of mine?
