      Description

      Annotate user-defined functions as strict and semi-strict.

      Definitions:

      • A strict function returns null if and only if one or more of its arguments are null.
      • A semi-strict function returns null if one or more of its arguments are null.

      The code generator should use these annotations to generate more efficient code.
