[Newbies] more of a general smalltalk question

[Sean Allen]

but i'm using squeak as my 'really learn smalltalk' einvironment so...

can any suggest any good reading, books, websites, whatever for  
learning the ins and outs
of how exceptions, signals etc work in smalltalk. i'm interested in  
both an 'end user'
perspective as a start but getting into the nitty gritty of the why of  
the implementation as well.
