When making a new "global type" like this in an init script::
from utility.struct import struct
__builtins__["struct"] = Struct
and then using the 'struct' type like this without any explicit import::
test = struct(a=123, b="test", c=(1,2,3))
... works in Python, but PyDev marks line as an error,reporting that name "struct" is an undefined variable.
