pure nothrow @nogc @safe TY implicitConvCommonTy(TY ty1, TY ty2);

If ty1 and ty2 are basic types, return the TY that both can be implicitly converted to.

Parameters:

TY `ty1`	first operand type
TY `ty2`	second operand type

Returns:

ty = common type, else Terror

pure nothrow @nogc @safe TY implicitConvTy1(TY ty1, TY ty2);

If ty1 and ty2 are basic types, return the TY that ty1 can be implicitly converted to to bring them to a common ty. It's symmetric, i.e. the operands can be swapped.

Parameters:

TY `ty1`	first operand type
TY `ty2`	second operand type

Returns:

ty = what ty1 should be converted to, else Terror
