Subject: Patch by Mark Day to allow from __future__ imports. Looks harmless
X-Git-Tag: v2.2a3~18
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=71707f3bb8be3a62518b43495881a5377ee82d0e;p=python

Patch by Mark Day to allow from __future__ imports. Looks harmless
enough, but may have side-effects because it preallocates a single
codeop.Compiler() to compile all statements the user enters.

Just: please review and retract/modify if necessary.
