Less flexible maybe, but works for me. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

As is the following gives assert on line 8 as expected,
uncomment bootstrap to get Internal error: e2ir.c 1251
template Instruction(int ir)
{
void match(alias s, alias m)(){ m.nextState(); }
}
struct T{
void nextState(){ assert(0); }
/*void bootstrap()
{
return Instruction!(0).match!(this, this)();
}*/
}
T t;
void main()
{
// t.bootstrap();
Instruction!(0).match!(t, t)();
}
With my pull, this code doesn't report ice, but raises following errors:
test.d(11): Error: template instance match!(this,this) cannot use local 'this'
as parameter to non-global template match(alias s,alias m)
test.d(11): Error: template instance match!(this,this) cannot use local 'this'
as parameter to non-global template match(alias s,alias m)
But I think this is a little harsh error. The nested template (function) match
in module template Instruction really needs only one context, that is enclosing
'this' given as alias parameters m and n.

Minimized test case and a workaround:
void match(alias m)(){
m.foo();//removing this line supresses ice in both cases
}
struct T{
void foo(){}
void bootstrap()
{
//next line causes ice
//match!(this)();
//while this works:
alias this p;
match!(p)();
}
}
void main(){}
Apaaerntly it has something to do with plain 'this' being mistreated in when
passed as alias.
