Hi John,

all pushed and gm2 now issues an error message (rather than an ICE :-)

$ gm2 Test.mod 
Test.mod:11:9: error: symbol 'CardType' is already declared in this scope, use 
a different name or remove the declaration
   11 |  EXPORT CardType;
      |         ^~~~~~~~
Test.mod:7:17: error: symbol 'CardType' also declared in this module
    7 | TYPE CardType = CARDINAL;
      |                 ^~~~~~~~

regards,
Gaius
