* micro implementation of rfc 149
refs https://github.com/nim-lang/RFCs/issues/149
* number/array/seq literals, more statements
* try fix number literal alias issue
* renew expectedType with if/case/try branch types
* fix (nerf) index type handling and float typed int
* use typeAllowed
* tweaks + const test (tested locally) [skip ci]
* fill out more of the checklist
* more literals, change @ order, type conversions
Not copying the full call tree before the typedesc call check
in `semIndirectOp` is also a small performance improvement.
* disable self-conversion warning
* revert type conversions (maybe separate op later)
* deal with CI for now (seems unrelated), try enums
* workaround CI different way
* proper fix
* again
* see sizes
* lol
* overload selection, simplify int literal -> float
* range, new @ solution, try use fitNode for nil
* use new magic
* try fix ranges, new magic, deal with #20193
* add documentation, support templates
