I have just started writing my first AngelScript scripts and would benefit from being able to write a template class in the script I'm writing; is this possible? The syntax I've tried is class MyClass<class T>, class MyClass<T> and template<class T> class MyClass. The ability to do this isn't shown in the documentation while the ability to register template classes from C++ is, so my suspicion is that it is not possible.

The current plan is to segregate game-specific logic as much as possible from the game engine; instead, programming all game-specific stuff in AngelScript. Things that can be written completely in scripts should be… the first to be written are the interpolators of values over time (to allow things like animation and movement) - these interpolators would benefit from not having a single value type to operate over, but instead basically “any numeric”, which would be good to get from templatization. These interpolators will never be registered from the C++ side and so will never get the option to be templated.

Another object that I have been thinking of making for a while now is effectively std::optional - while it may be good to do this from registration, writing it in pure AngelScript would be better in my opinion.

There are of course different ways to achieve that, more verbose and less C++-y in my opinion. Maintaining parity between the possible registration elements and pure-script elements would also be good I think.
