002 keyword collision

✓ Passing This code compiles and runs correctly.

Code

// Test: Keyword collision - two modules define same keyword
// This should produce an error at ~process() usage
~import lib_a
~import lib_b

// Using ~process without qualification - should error because both lib_a and lib_b define it
~process()

Frontend must reject with:

Ambiguous keyword

Error Verification

Expected Error Pattern

Keyword collision should cause compilation error

Actual Compiler Output

ERROR: Ambiguous keyword 'process' - defined in:
  - lib_a:process (from lib_a)
  - lib_b:process (from lib_b)
error: AmbiguousKeyword
