Well, importing itself can be done easily like this:
{.emit: """
#define HELLO_WORLD 10
""".}
var x {.importc: "HELLO_WORLD", nodecl.}: cint
echo x
This will generate `LOC1 = nimIntToStr(((NI) (HELLO_WORLD)));`, which directly
uses the name. Good.
But what if the user:
x = 20
echo cast[int](addr x)
Nim compiler produces no error for these, and the errors are reported by the C
compiler, which looks kinda cryptic.
What I want is, something like:
let x {.importc: "HELLO_WORLD", nodecl.}: cint
where Nim compiler reports errors on modification or taking address of `x`,
while the usage of `x` generates `HELLO_WORLD` the symbol instead of `10` the
value.
