To summarize my plan of action for the list:

I might as well speak up -- we're still using the codebase you mentioned
in several different situations. If I could have just hooked the Perl
parser into the lexer framework, I would have long ago, but that doesn't
work for editing buffers, which usually do not contain a valid Perl string.
You absolutely need to recover from syntax errors as quickly as possible,
and not be too clever. If this means the user has forgotten to close a
quote, the rest of the buffer should be colored to reflect that.
Thanks for the update.
Kein-Hong has covered the most troublesome parts, which come down to the
use of barewords and ambiguous operators (qw@/ ? <<@ are the main
culprits).
Given the enormous effort that a parser will require, I will
instead focus on small wins with the current code until such an
approach is exhausted. If delimiter-related failures are reduced
to a very low level, then the "annoyance factor", which is usually
due to the said delimiter-related failures, will be almost totally
eliminated.
