Comment 2 Philipe Mulet CLA 2005-04-26 04:42:27 EDT 
Problem is in parser which discard the statements inside the #bar() method.
Comment 3 David Audel CLA 2005-04-26 06:24:55 EDT 
Enum constants are parsed during diet parse and this parse jump over method body.
We must force the no diet mode for enum constant arguments.
Comment 4 David Audel CLA 2005-04-26 07:23:30 EDT 
inside the grammar

EnumConstantHeader ::= EnumConstantHeaderName Argumentsopt

must be replaced by

EnumConstantHeader ::= EnumConstantHeaderName ForceNoDiet Argumentsopt RestoreDiet
