Carpalx is a modifiable keyboard layout system that is based on applying a quantitative model of typing effort. QGMLWB is the fully optimized layout for letters.

Pros
Pro Punctuation is in the same location as QWERTY
If you already know QWERTY you don't have to relearn the punctuation, with the single exception of the ;:
key which is in QWERTY's P
position, like Colemak.
Pro ZXC don't move compared to QWERTY
Like Colemak, the common undo, cut and copy Ctrl-commands don't move from their QWERTY positions. The V
(paste) key does though.
Cons
Con Punctuation is not optimized
Programmers have to use punctuation a lot, but (except for the ;:
key, like Colemak) punctuation hasn't been moved from their positions on QWERTY. In fact, the non-letter characters , . - " _ ' ) ( ; 0 1 = 2 :
are used more than the least-frequent letter z
in a reasonable English corpus. Not optimizing punctuation at all, especially for programmers, is nonsense.
Con Doesn't favor the right hand
For right handed users, this keyboard layout doesn't use the usually stronger right hand more than the left, infact it sometimes favors the left hand more.
