There is a very simple breakpoint mechanism in Pharo (in Squeak, too,
but
it was a bit broken there).
To try: There is a "toggle break on entry" item in the menu of methods
in the
old browser.
Technically, this just recompiles the method with a call to #break at
the beginning.
Could be improved a lot.
