Description

proc h(): auto =
  proc(_: bool) = discard
const m = h()  # if this is declared as `proc m(_: bool) = discard`, builds, but `let` doesn't matter
static: m(true)       # i.e. it knows at compile-time it's something callable
block:
  proc m(_: int) = discard
  m(true)   # builds if this is `f.m(true)`, i.e. refers to own module name
