Currently, tolk-tester can test various "output" of the compiler: pass input and check output, validate fif codegen, etc. But it can not test compiler internals and AST representation. I've added an ability to have special functions to check/expose internal compiler state. The first (and the only now) is: > __expect_type(some_expr, "<type>"); Such a call has special treatment in a compilation process. Compilation fails if this expression doesn't have requested type. It's intended to be used in tests only. Not present in stdlib.
