You can examine $context->{LOAD_TEMPLATES} to find current component and
then get it's full path. This sample code works when called from template,
but not from BLOCK:
my $stash = $context->stash();
my $component = $stash->get('component');
my ($provider) = grep { $_->{HEAD}[2] eq $component } @{
$context->{LOAD_TEMPLATES} };
my $path = $provider->{HEAD}[1] if $provider;
Anyway, linking to file name seems to be a bad practice, because some
templates may have no file name at all - it could be hard-coded in perl code
or served from database.
