Subject: [ruby-core:28015] RCR: RUBY_VERSION_INT

Situation:

Currently in a .rb file, to determine if you're on 1.9 versus 1.8 is
not all that straight forward.
Ex:  To tell you're on 1.9.

RUBY_VERSION > '1.8'

except that that fails--instead you must use

RUBY_VERSION >= '1.9.0'

or

RUBY_VERSION > '1.9' # using > 1.9 to determine that you're running is
a bit hard.

Suggestion:

add new constant:

RUBY_VERSION_INT (or whatever)

like 190, 191, etc.

That would simplify the logic quite a bit.  It hurts my head every
time I have to write a boolean to determine if I'm on 1.8.
Thoughts?
