Note though that a lot of the problems with GC in crystal can be worked around by replacing classes with structs. The latter are passed by value and allocated on the stack. There is also access to pointers and manual allocation if that should be needed (though that will end up with roughly the same lack of memory safety as in C) to optimize a hotspot.
