Sorry for the delay, I've been mulling over what to do about this and haven't been fully satisfied with any of the answers. Not requiring the checks for now would definitely make this faster to implement though. My biggest concern is that, in C++, the types can actually play a significant role in the implementation of a given operation, and many of the things that go into determining what type may be returned are things that we don't want to have visible in Cython. Features like SFINAE and enable_if may be difficult for us to support, but syntactically, they don't use much fancy syntax. At some point, it seems to be in the best interest of our users if we let the C++ compiler finish off the type checking rather than requiring that all the type information be present in Cython. As near as I can tell, adding type specifiers to non-type template parameters won't put us into much murky water though, so I'll take another shot at adding the new syntax. Thanks for following up here. Best, -Ian Henriksen
