class A
{
    int x[];
    void read_array(alias var, T = typeof(var))(...){ return; }
    void fail(){ read_array!(x)(); }
}

- test.d:5: template instance cannot use local 'x' as template parameter
- gcc version 4.1.3 20070831 (prerelease gdc 0.25, using dmd 1.021)

Moving [read_array] out of [A] or making [x] static "fixes" it. But i don't really want to have to pass a 'this' pointer to it every time i use it.

Is there any other/better way to produce the above in a template (without [block] being a specific type)?

	    TypeInfo t  = typeid(T);
	    size_t size = ((t.next) ? t.next.tsize : t.tsize) * n;
	    block = cast(typeof(block)) new byte[size];

so passing a uint32_t[] as [block] with [n = 10] would allocate 40 bytes and block.length would be 10. Or passing a uint32_t* to it would simply assign the allocated blocks address to it.

I don't think you can have non static template functions in a class

Of course you can (though the spec still says otherwise).  You can't have _virtual_ templated methods in a class.  Templated methods are implicitly final.
