This interests me - I can type code just about as fast as I can type standard text, but things are very different for my husband. He is (mild-moderately) dyslexic, and so typing plain text probably works out to about 10 wpm after corrections.
Where code is concerned, however, I've never seen him make a mistake. Until I first saw this I never considered that perhaps a different part of the brain processes different languages.
Anybody know whether it's possible to have problems with one (spoken, not programming) language and not another?
