I found that strange and inconsistent.
I'am wrong?
Read Peter Hugosson Miller's message. instVarNamed: is like instVarAt:, in fact
instVarNamed: instVarName
� � ^self instVarAt: (self class allInstVarNames indexOf: instVarName)
but that's slot and better is
instVarNamed: instVarName
� �^self instVarAt: (self class
instVarIndexFor: aString asString
ifAbsent: [self error: 'no such inst var'])
any clearer? �i.e. instVarNamed: is sent to instances to access their inst vars, not to classes to access meta data about their inst vars.
