My initial thought about this was: it adds complexity that wasn't there
before. If you write a syntax highlighter for Gambas right now, you do not
have to keep track of state between lines. You can analyze all lines
independently of each other, in parallel, in a random order if you wish.
A fully-fledged parser of course doesn't benefit this greatly from it,
and the Gambas internals seem relatively agnostic about if, but a syntax
highlighter is what I'm currently working on (in vimscript, if you have
to ask, so keeping state *is* an issue).

But, this property is lost anyway once we get line continuation characters,
by Bug#1540.
