couldn't the first be improved more by allowing something like:
T opOpAssign(string op : in("+", "-", "*", "/", "%", "^^", "&",
"|", "^", "<<", ">>", ">>>"), T)(T x)
The `in` there is my attempt to disambiguate between this type
of constraint and what I view as the most likely syntax for
built-in tuples.
While a static switch could be a little handy (I have desired it
few times, despite a static foreach is much more needed), there's
no strong need for that "in", You can use something like
(untested):
T opOpAssign(string op, T)(T x)
if ("+ - * / % ^^ & | ^ << >> >>>".split.canFind(op))
