I am looking to implement a hand-coded lexer/parser for the

Why?
Primarily because I am [not] up to speed with parser generators.

Listen,
parsing is hard (well, unless your language is LISP). You'll end up
wasting lot of time on debugging your parser. Worse, if later you'll
want to extend your grammar, you'll likely realize that too is hard
in a handwritten parser as you'll have to modify a lot of it. Parser
generators exist for a reason; they do a tremendous amount of mundane
work instead of you. I would never write a lexer/parser by hand,
unless the goal is to amuse myself with exactly that.
Seconded.
Yeah, let's start writing a parser generator !
There, you can't say we didn't try to warn you :-)
