Synonyms in PML Macros and Functions
The user may use
synonyms
in macros, although they can
not
use them in PML Functions.
This restriction was introduced because changing a synonym (which is global to the whole program) can cause an unintentional change in behaviour of individual macros.
There is also a large performance penalty on every line of PML executed where synonyms are permitted.
