Re: [Pharo-dev] MetaLink to conditionally skip a method execution based on an arg

Hi.

Imagine I have method a: and I want to skip the execution (return self or nil or whatever) when a: is evaluated with parameter 0. I have tried to add a meta link which will run instead of the method with a condition, but the condition did not work… I have tried to implement the metallic method to do nothing if the arg is 0 otherwise to perform the method, but I end up with an infinite loop…

Did anybody do something like that already? Any suggestions?
