[squeak-dev] thisClass

Hi All,     thisContext method methodClass theNonMetaClass selectors do: [:sel| ...

I believe it should be a kernel method.

If you're want only to short-cut writing:

     thisContext method methodClass

then why use other selector than methodClass?

Btw, in Pharo image (which i currently running) there is already such
thing, implemented as:
ContextPart>>methodClass
        "Answer the class in which the receiver's method was found."
       
        ^self method methodClass ifNil:[self receiver class].

A method stamp reads:
md 2/17/2006 18:41 · debugger access

so it looks like it been there for a while.
