I just discovered the following behavior:
C:\Documents and Settings\dave>python Python 2.3 (#46, Aug 25 2003, 18:37:29) [MSC v.1200 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information.
prefix = ['foo', 'bar', 'baz'] prefix += 'bomb' # meant to write prefix += [ 'bomb' ] prefix ['foo', 'bar', 'baz', 'b', 'o', 'm', 'b']
Is it new and/or intentional? I would have expected an error from the +=. I was very surprised when my error "passed silently".
