Yes, but if you execute, say:
Object compile: 'testSelf: self'
Object compile: 'testNil: nil'
Object compile: 'testTrue: true'
Object compile: 'testFalse: false'
It compiles just nicely. So the bug seems to be the treatments of
nil,true,false,self as variable nodes instead of literal constants.
Variable nodes may be silently shadowed in some circumstances, literal
constants cannot, e.g.,
Object compile: 'test123: 123'
Object compile: 'testString: ''string'''
Object compile: 'testSymbol: #symbol'
all correctly fail.
