cat > bug.d << CODE
void foo(alias pred)()
{
}

void bar()
{
    foo!(a => a + 1)();
}
CODE

dmd -H -o- -c bug

--------

The lambda template is not emitted and leaving
the header with an unknown symbol.

foo!(__lambda2)();
Comment 1 Kenji Hara 2013-10-11 07:15:04 UTC 
With 2.064 git-head,

void foo(alias pred)()
{
}
void bar()()   // Make template to output function body in di file
{
    foo!(a => a + 1)();
}

dmd -H -o- test.d

Outputs:
// D import file generated from 'test.d'
template foo(alias pred)
{
	void foo()
	{
	}

}
template bar()
{
	void bar()
	{
		foo!((a) => a + 1)();   // correct
	}

}
