(* NOTE: The identifier as a variable test has some special cases.

26 |
* Namely, when using IL operators as variable names.
|
|
|
27 |
* Even though the syntax of the IL language would not result
|

28 |
* in ambiguities in the above case, our parser does not currently

32 |
* The following test code must therefore consider two possibilities:
|

33 |
* - if the identifier under test is an IL operator
|
|
|
34 |
* - if the identifier under test is not an IL operator
