Since we're minimizing source-breaking changes, the issue is settled in my view, having been proposed, commented upon, reviewed, and rejected.</blockquote></div></div></div></div></blockquote><p></p></div><p style="margin:0px 0px 1.2em!important"></p>
<p style="margin:0px 0px 1.2em!important">Ok, I understand, you probably consider the syntax in question <code style="font-size:0.85em;font-family:Consolas,Inconsolata,Courier,monospace;margin:0px 0.15em;padding:0px 0.3em;white-space:pre-wrap;border:1px solid rgb(234,234,234);background-color:rgb(248,248,248);border-radius:3px;display:inline">{ param -> Int in ... }</code> closer to the short form <code style="font-size:0.85em;font-family:Consolas,Inconsolata,Courier,monospace;margin:0px 0.15em;padding:0px 0.3em;white-space:pre-wrap;border:1px solid rgb(234,234,234);background-color:rgb(248,248,248);border-radius:3px;display:inline">{ param in ... }</code> than to the full form <code style="font-size:0.85em;font-family:Consolas,Inconsolata,Courier,monospace;margin:0px 0.15em;padding:0px 0.3em;white-space:pre-wrap;border:1px solid rgb(234,234,234);background-color:rgb(248,248,248);border-radius:3px;display:inline">{ (param: Int) -> Int in ... }</code></p>
<p style="margin:0px 0px 1.2em!important">So when applying analogy, it makes more sense to allow the omission as in the short form than to disallow as in the full form. I have to agree. So, -1 to all points of the OP.</p>
