Idea: replace length-specific overloads with TS 4.0 variadic tuple types

TypeScript 4.0 added variadic tuple types.

Mammoth’s variable-length methods like .select(...) are currently implemented with one signature overload for each length of arguments, from 1-75. Can/should that be replaced with variadic tuple types?

Potential advantages:

1. My IDE occasionally freezes for ~3 seconds when trying to show the autocomplete for methods like .select(...). I wonder if that’s because of the number of length-specific overloads.
2. I wonder if things like this will be easier: https://github.com/Ff00ff/mammoth/issues/218. (I don’t actually know…)
3. Potentially better type error messages.

Thanks, this is fixed now. I’ll try to apply this technique to the other many signature overloads like returning().

Go for it! (If I get another chance to look at this, I’ll update this issue.)
