You can get the code to compile with two changes:
bool function(T)(T val1,T val2) ptr=∁
should be:
bool function(T val1,T val2) ptr=&comp!T;
The function pointer itself isn't a template, so it doesn't
need the (T) parameter. Instead, since it is inside a template,
you can just use the T from the outside directly.
Moreover, comp has compile time arguments, so you can't take
the address of it without forwarding the arguments. So instead
of &comp, you use &comp!T - passing the T from the outside to
the comparison function too.
and also
int partition(T)(T[]list,bool function(T)(T val1,T val2)ptr,int
should be:
int partition(T)(T[]list,bool function(T val1,T val2)ptr,int
Again because the pointer isn't a new template, it should just
use the type T from the outer argument list.
