Fix bug in SHParserST80: Wrong styling after blocks with arguments without statements
If you mean that Shout should accept [ :x ], then no, I'm pretty sure that's not valid smalltalk syntax, even if Parser accepts it. The vertical bar, even though I consider it unnecessary in all cases, is mandatory when there are arguments.
I only got to know this "shortcut syntax" because eliot used it either Cog or somewhere in trunk when preparing something (Spur? full block closures? I forgot). So this is a syntax idiosyncrasy that is in active use, not only "old code".
Either we forbid it in the parser and change all of the image or allow it in Shout.
Can you give me examples? I suspect those are just typos, which the parser accidentally accepted (and Shout as well before my fixes).
