Dump mixins (preprocessed/generated) code

[Domingo Alvarez Duarte via Digitalmars-d-learn]

Hello !

I'm trying to make MiniD/Croc work with dmd2 and I'm having a 
problem with this code and I want to know how to dump the 
generated code to understand what's happening.

How that can be done ?

debugmixin.d-mixin-15(15): Error: no identifier for declarator 
char[]

-----debugmixin.d
/// Eheheh, I has a __FUNCTION__.
const char[] FuncNameMix = "static if(!is(typeof(__FUNCTION__))) 
{ struct __FUNCTION {} const char[] __FUNCTION__ = 
_getJustName(__FUNCTION.mangleof); }";

template apiCheckNumParams(const char[] numParams, const char[] t 
= "t")
{
	const char[] apiCheckNumParams =
	"debug assert(" ~ t ~ ".stackIndex > " ~ t ~ ".stackBase, 
(printStack(" ~ t ~ "), printCallStack(" ~ t ~ "), \"fail.\"));" ~
	FuncNameMix ~
	"if((stackSize(" ~ t ~ ") - 1) < " ~ numParams ~ ")"
		"throwStdException(" ~ t ~ ", \"ApiError\", __FUNCTION__ ~ \" - 
not enough parameters (expected {}, only have {} stack slots)\", 
" ~ numParams ~ ", stackSize(" ~ t ~ ") - 1);";
}

void setHookFunc(void* t, ubyte mask, uint hookDelay)
{
	mixin(apiCheckNumParams!("1"));
}

void main()
{
}
