another change planned for Squeak 6 is eliminating ContextPart & MethodContext in favor of Context.  In reviewing the (very few) changes necessary I came across the following:

MethodContext>>printString

"Answer an emphasized string in case of a breakpoint method"

^(self method notNil and: [self method hasBreakpoint])

ifTrue:[(super printString , ' [break]') asText allBold]

ifFalse:[super printString] 

Seriously?  I don't object to modifying [Method]Conext>>printOn: to include [break] but having printString answer a text seems completely broken to me, and overriding printString is a hack; printOn: being the operative method for producing self-descriptions.  Should we nuke it and add [break] to printOn:? Or...?
