Nevertheless, I found two issues: one, ParameterTypeTuple doesn't work

Could you or someone else expand on this?

An example in Higher Order Perl is memoizing a RGB to CMYK function:
ubyte[4] rgb2cmyk(ubyte[3] rgb)
{
ubyte[4] result = void;
result[0] = cast(ubyte)(255 - rgb[0]);
result[1] = cast(ubyte)(255 - rgb[1]);
result[2] = cast(ubyte)(255 - rgb[2]);
result[3] = min(result[0], result[1], result[2]);
result[0] -= result[3];
result[1] -= result[3];
result[2] -= result[3];
return result;
}
Trying to memoize this yields a range error at runtime.
