Subject: QuickCheck tests now terminate successfully.
X-Git-Url: https://git.rkrishnan.org/pf/content/simplejson/frontends/CLI.rst?a=commitdiff_plain;h=308c77eccabe0f1f66959eac3bf0b1686570b0e8;p=functorrent.git

QuickCheck tests now terminate successfully.

The trick is to reduce the amount of data we generate for recursive
types. The hint is in the QuickCheck manual.
