This is still an open issue, isn't it? (oh, it would be so comfortable if we had something like GitHub issues ...)<br>
<br>
<br>
And just one related question: According to the BNF John mentioned --<br>
<pre><block constructor> ::= '[' <block body> ']'
<block body> ::= [<block argument>* '|'] [<temporaries>] [<statements>]
<block argument> ::= ':' identifier
</pre>
(from the <a href="https://wiki.squeak.org/squeak/uploads/172/standard_v1_9-indexed.pdf#page=21,22" target="_top" rel="nofollow" link="external" style="color: rgb(0, 79, 135); font-size: 1em;">ANSI Smaltalk Standard</a>)<br>
-- the following should be valid syntax as well, shouldn't it?<br>
<br>
<pre>[|] value.
</pre>
<br>
The explanation is that, according to Wikipedia, an asterisk in the BNF stands for "0 or more times". So provided that there is not a mistake in the official standard document, shouldn't we support the above example?<br>
<br>
Which is the exact standard we are following? The Blue Book? The ANSI Smalltalk Standard?<br>
