Overview: Type checking
Type checking is introduced to the VTCL language in a backward compatible way. This means that any existing VTCL transformation should compile without modification.
As the main extension of the language, one can add type information to
- all variables defined locally with the let rule
- a parameter of an ASM rule, graph pattern or graph transformation rule
- for the parameters and return values of ASM functions
