Often, when I try to file in some code that looks interesting and has
been posted to this list, the filein starts OK but then I get the
issued from the compiler.
Now, as a moderately accomplished Smalltalker, I poke around in the
debugger and I find on the stack something like
^ TheWorldMenu methodsFor: 'as yet unclassified' stamp: 'mdr
and I figure out that because of the way that a fileIn actually
executes the code in the file the problem is that a class called
TheWorldMenu is being extended by the filein, but my image does not
define that class at all, hence the problem.
However, if I were even more of a novice than I am, I think that I
would be really confused an surprised by this MessageNotUnderstood,
when what I might expect is a warning like "undefined class
TheWorldMenu". Better, I might expect the filein to complete, and
then get a warning that I also need to filein the class "The
Thinking about this even more, what both the novice and myself really
need is some sort of dependence mechanism that would tell me where
the H*ll to go looking for "TheWorldmemu".
