Nicolas Cellier uploaded a new version of Traits to project The Trunk:

Ancestors: Traits-ar.283
Don't use closeTo: when comparing compiledMethod.
Either two methods are equals or not (or we could fuzzify String equality to with sameAs: or other trick....).
The hack was previously necessary due to roundoff errors in printing and reading a Float.
This is not the case anymore: Float literals now storeOn: and readFrom: exactly..
=============== Diff against Traits-ar.283 ===============
Item was changed:
----- Method: CompiledMethod>>sameTraitCodeAs: (in category '*Traits-NanoKernel') -----
sameTraitCodeAs: method
"Answer whether the receiver implements the same code as the
argument, method. Does not look at properties/pragmas since they
do not affect the resulting code."
