Are there any disadvantage to using computed goto ? (I'm not aware of any but
could've missed something)
If not, why not make {. computedGoto.} implied automatically for all switch
statements over enum (or finite range) variables (see
[https://nim-lang.org/docs/manual.html#pragmas-computedgoto-pragma](https://nim-lang.org/docs/manual.html#pragmas-computedgoto-pragma))
and deprecate that pragma which would become a noop. As is the case for
{.computedGoto.}, switch statement would transform to a computed goto only if
backend supports it.
