TypeExpression rejected when used for a parametric alias-exp

test case

unit temp;

alias Exp(T) => T;

enum PropMin
{
    e0 = 1
}

static assert(PropMin.min == 1);
static assert(Exp(PropMin).min == 1);     

output

temp.sx:11:19: error, expression PropMin represents a type and has no value
temp.sx:11:18: error, starting from here

notes

Both static assertions should be verified.
