Merits of the patch aside (I like the idea!), it still doesn't get to
the core of *why* Guido suspects there are benefits to making the
Just consider how to handle the more complex case of code like:
CountOfLumberJacksAvailable = 12
CountOfLumberjacksAvailable = CountOfLumberJacksAvailable + 1
Code, which you will notice, generates no "errors"...
Guido's assertion (which I believe) is that we humans are not used to
reading case as being significant to the meaning of a word -- in
addition our ability to even perceive the case of a word is pretty
poor. I'm sure that there are studies in the cog-sci reading-
comprehension area that support this result and demonstrate that memory
for case is pretty pathetic.
Guido is developing a language product for enabling people to use
computers -- not training people to (rearrange their perceptual
systems to) think the way a computer does.
