I think that cast is binary operation with value and type. And I made
groundless patch(I tested with dmdfe and gdc-2.0-dev). This idea break
old opCast call and have side effects like allowing "cast(value)". But
it support other pattern like "type + value". How about this idea?
#sorry for my poor English
val_a op val_b (Example: a + b)
val_a.opfunc(val_b)
val_b.opfunc_r(val_a)
val op type (Example: a + B, cast(B)a)
val.opfunc!(type)()
type.opfunc_r(val)
type op val (Example: A + b)
type.opfunc(val)
val.opfunc_r!(type)()
type_a op type_b (Example: A + B)
type_a.opfunc!(type_b)()
type_b.opfunc_r!(type_a)()
