the logic behind using them is that it make the code much more readable.
a good example is pack_start:

$vbox->pack_start ($widget, 1, 1, 0);

is (arguably) less clear than

$vbox->pack_start ($widget, TRUE, TRUE, 0);

in that it's obvious that you're not putting sizes in there, that
they're booleans. other functions have similar advantages,
$widget->set_sensitive (TRUE) is better than $widget->set_senstitive (1)
b/c it's clear that it's on or off, maybe it's something that you can
set how sensitive it is, and TRUE/FALSE shows that's not the case. it's
not a big deal. using 0/1 aren't wrong by any means, it can just make
for clearer code.
