Nested assignments misparsed #32

Closed jkoppel closed 7 years ago

jkoppel commented 7 years ago

"x = y = 1" gets incorrectly parsed to "x, y = 1", which gives an error when executed.

The fundamental problem is that assignments are treated as statements in the AST, even though they are not statements in the grammar.

Thanks for the bug report. It was a problem with the pretty printer. Has been fixed in 7f6d3b2bb667394e73fb2d3be87cdd5f375ece18, thanks to a pull request from @mkovacs. Bumped version to 0.5.5.
