Define "trickyness" in for-loop pattern

[bradym80]

On line 35 of the for-loop pattern the following comment appears.

// optimization 3 - substitutei++withi = i + 1ori += 1to avoid excessive trickiness

Could you elaborate on "excessive trickiness"?

@bradym80 I was wondering the same thing. My assumption was that i = i + i is easier to understand since i++ requires some previous knowledge about this iterator. Not sure if there are some performance differences.

Anyway, I find i++ beautifully succinct and not tricky at all. :)

When you write these expressions as i = i + 1 it's clear what the intent of the programmer was and easier to find bugs in the code where as i++ prevents excess craftiness.

Well, if i++ is too tricky I find it funny that in preferred 1 and 2 you use i-- :)
