I'll open a documentation fix after the merge.

This looks reasonable; we already allow this for asm blocks.

I'm not too thrilled with this language change. First off, having the parens sometimes makes it confusing - when does one need them and when not? Second, adding more syntax without new capability and just as long just seems pointless. Third, adding new syntax that is redundant with existing syntax by just shuffling the order of keywords around may cause problems when significant new features are added later. Fourth, then we'll have to decide on what the "preferred" syntax is for style, and bikeshed about it, and write a style document, and add it to dfmt.

I talked with Andrei about it, and we came to the conclusion that this change would cause problems for future possible enhancements to unittests.
