Parameterized Syntax: Undeclared type error #1775

Open TarVK opened 1 year ago

TarVK commented 1 year ago

Describe the bug

When using a parameterized syntax type, type reification does not appear to work. It errors mentioning that the type is not declared

To Reproduce

Steps to reproduce the behavior:

  1. Declare: 
    syntax Opt[&K] = | &K;
syntax P = "a";
  2. Try to execute #Opt[P]
  3. Observer error: "Undeclared type: Opt"

Expected behavior The reified type should be returned. This does work properly when using Opt elsewhere, such as:

syntax Q = Opt[P];
#Q;
