Oh , well it seems works only for selectors, but not for ivars/classvars :(
i put the
MyClass class>>allowUnderscoreSelectors
^ true
on previously defined MyClass, and then tried to add ivar with underscores:
Object subclass: #MyClass
instanceVariableNames: 'a_b_c'
classVariableNames: ''
poolDictionaries: ''
category: 'OpenGL-Specs'
after accepting it, i got no error (what is strange), but instead ,
the class having 3 ivars:
Object subclass: #MyClass
instanceVariableNames: 'a b c'
classVariableNames: ''
poolDictionaries: ''
category: 'OpenGL-Specs'
This is inconsistent. It should either throw an error or accept the
variable name with underscore, but not silently turn
'a_b_c' into 3 separate ivars.
