A new class (
merged this week into Pharo 7) called "OCCompilerDynamicASTPlugin" allows for the dynamic creation of compiler plugins
Object compiler
addPlugin:
(OCCompilerDynamicASTPlugin
newFromTransformBlock: [ :ast | (RBParseTreeRewriter replaceLiteral: 42 with: 'meaning of life') executeTree: ast. ast. ]
andPriority: 0
);
evaluate: '42'.
This would give 'meaning of life'
