[fpc-pascal] Underscores in numerical literals - grouping

I like the concept, but, if I'm using a constant that goes beyond the
millions, I'd add a comment to what the number is in US format, and tag on
what exactly it means, or make the variable name itself mean something.
const maxLongint = $7fffffff;
const maxLongint = 2147483647;
is a bit of a pain, I agree.
That said, underscores aren't what I'd use.
I love the idea of the IDE (ANY IDE, not just Pascal based) doing some kind
of code highlight for large numbers. Something simple, like underlining
every other group of 3 in large numbers, or every other hex pair, or every
8 binary set.
As for the mono-spaced, no, not ridiculous. If memory serves me correct,
I believe you're as old-school as I am when it comes to code (My teeth cut
on Vic-20), but I've always preferred mono-spaced fonts in my IDE versus
variable width, JUST on the primary basis of legibility of the code itself,
ignoring the 'gravy' of lining up text within the code. I always
terminal/system/consolas, even in Notepad/PSPad. I barely tolerate
variable width font in GMail as I can't change the font easily (But you've
sparked an idea >:] ). Figuring out if I'm using a capital I versus a
lower l versus a | is quite annoying (Capital EYE versus lower ELL versus
pipe). Most of the apps I write (for myself) are list based, or require
special formatting are typically fixed width as aligning text is much
easier, and I don't have to code special considerations for W and 1 width
differences. Forget about the form UI, but even lining up variable
declarations and definitions, procedure, function declarations within
classes, much easier with fixed width.
