David:
-1 % 16 = -1Shouldn't that be 15? It seems like the sign is ignored for the modulo.Is this a bug or intended behaviour? The Python implementation returns here, as expected, 15.
It's a localized but important design bug of languages like C that D has carried over for backward compatibility reasons. D % has caused bugs in my code. I suggest to not use the built-in % on numbers that can be negative, unless you really know what you are doing.
