Here is how I would attack the new implementation :

MyClass class>>nan
    ^NaN

(Float class>> #nan) = (MyClass class >> #nan) -> MNU nil
doesNotUnderstand: isNan

MyClass>>a0
  ^0.5
MyClass>>a1
  ^0.5s1
MyClass>>a2
  ^0.5s2

(MyClass>>#a1)=(MyClass>>#a2)
(MyClass>>#a0)=(MyClass>>#a2)


MyClass class>>componentMask
        ^ComponentMask ifNil: [ ComponentMask := 1023 ]
MyClass class>>componentMax
        ^ComponentMax ifNil: [ ComponentMax := 1023.0 ].

(MyClass class>>#componentMax) = (MyClass class>>#componentMask). -> false
MyClass componentMax; componentMask.
(MyClass class>>#componentMax) = (MyClass class>>#componentMask). -> true
(MyClass class>>#componentMask) = (MyClass class>>#componentMax). -> false

Of course, these are unlikely, but...

Nicolas

(Float class nan) = (MyClass class nan) -> MNU nil doesNotUnderstand: isNan
