`do` construct, analogous to `let` #42

Closed AndreVanDelft closed 8 years ago

AndreVanDelft commented 8 years ago

let conveniently introduces a tiny code fragment, corresponding with a neutral element in ACP.

Similarly, the word do should introduce a normal code fragment, corresponding to an atomic action. And do* should introduce a threaded code fragment.

This will even further reduce the role of bracket pairs.

With the keyword do we would get an ambiguity conflict with the do-then-else construct. So we have to find a better word. Maybe act?

Sorry to bother open this again, but I think that

the overloaded use of do may also be confusing to the programmer
there is no uniformity between do and do*
there are no likewise alternatives for {? ?}, {. .} and {... ....}

Therefore I suggest to replace this do by do!, and to add do?, do. and do...for the missing cases. Ok?
