Don't export @set

[jariji]

OhMyThreads.@set is pretty niche functionality and it clashes with Accessors.@set. Currently it's exported, would it be okay to not export it?

It's not at all niche if you use the @tasks macro API.

I would recommend that you only explicitly import/using the bits that you need (e.g. using OhMyThreads: tmapreduce) rather then just doing using OhMyThreads.

While the simple using X is, unfortunately, very common in Julia codes, it is quite generally an anti-pattern that doesn't scale well. (Any export that a package might add over time could break your code, because clashes like the one you mention here could occur.)
