Min/Max functions

[Dietr1ch]

I'm in need for something like min(num_cpus(), K) to avoid underlying issues with some tools.

Is there a good way of getting that? I think I'm a bit held back by #11 to use the shell, but maybe there's a better workaround.

I think I'm a bit held back by #11 to use the shell,

How so? Why not using the shell() function?

I completely missed that function when reading the docs, thanks!
