comment Clean & efficient bounding box non-intersection test
@BenP1192 you should post that as an answer. I found that you can include the bounding box in RegionIntersection, RegionIntersection[Line[ab], Line[cd], Rectangle[]]

comment How to define a bivariate skew normal distribution?
The Plot3D example doesn't work because the probability distribution needs to be pre-evaluated. Try adding an Evaluate in your code for SN. As for the random variates, you are still probably going to have to create your own method.

comment How to define a bivariate skew normal distribution?
Univariate is generally easy because one can use the inverse cdf if all else fails. Multivariate will probably never be implemented in full generality. Also, pretty much everything exists in closed form for multivariate normals so special case code exists for those.

Sampling from user defined multivariate distributions isn't implemented. You will need to somehow use built in distributions or define your own method for sampling.

comment List all “duplicate” elements in Tally
@Mr.Wizard infix is a lovely obfuscator. If only there were short aliases for built in symbols for the purpose of code golf. Accessed via On["Golf"]. Though <<Golf' is probably better.

@Mr.Wizard I'm one as well but clearly my kung fu is not as strong as yours :)

Possibly GatherBy is what you need but without more specifics I can't say for sure.
