how about 'if you are proficient at another language, feel free to skip to chapter x'? and put the generalized stuff at that point

[zedshaw]

If you really are that proficient, you should be able to figure out what you can skip.

I'm not so sure about that. The devil's in the details - you might think you know something well enough to skip it, but get caught out later.

Sometimes due to language discrepancies, skills don't transfer and there is no easy "feel free to skip to chapter x".

For example, a conversant Python programmer's idea of string, and strings in C are 2 different things. A conversant C programmers idea of looping is different from idiomatic looping in Racket(and other lisps).

actually you are right, it completely doesn't work in that example
