In addition to the feature mentioned by Gunther in his reply to your
question (params' stickyness), it's about not clutterring your code with
HTML. Embedding HTML makes it harder to some degree to understand the Perl
code fast. Unless you are used to it :)
it's also about smart construction of HTML code using map() and similar
constructs:
print table(-align => 'center',
tr( map { td($_) } qw(foo bar) )
);
or even more usual non-hardcoded use:
print table(-align => 'center',
tr( map { td($_),td($rows{$_} } keys %rows )
);
now try to write the same code using HERE construct... you get the idea...
Anyway, I never use CGI::Q (function API), and always use OO interface,
which is faster in case of CGI.pm, since its API functions aren't true
functions and are resolved at run time. See the code and notes in the
guide if you need a proof.
Of course a better way to handle this is to use templates. TT is very
good, but we all wait for Perrin's talk at OSC which will summarize the
long thread we had here some 6 months ago and add his own experience.
