<div>One could introduce the @ operator to get a reference to a
block of code.<br>

The sequence "@(identifier" is already a valid sequence (because
"@(SomeVar)" is valid) and I'm definitely and absolutely against
introducing another ambigous syntax as I already have enough
headaches with Delphi's generic syntax.<br>

<div>The "result" variable is also ugly. You could make "if" an
expression:<br>
</div>
<div><br>
</div>
<div>
<pre class="moz-quote-pre" wrap="">Sort( @(left, right) begin
result :=
if left < right then -1
else if left > right then 1

Allowing if (and case) to be an expression, too, is something I'm
still toying with independantly of this...<br>

</pre>

</div>
Then the begin end could be removed too. Make @:= an operator to
turn an expression to a function</div>
<br>
<div>
<pre class="moz-quote-pre" wrap="">Sort( @(left, right) :=
if left < right then -1
else if left > right then 1
else 0;
);
</pre>

I personally would have a bit more verbose syntax though it would
have the same problem regarding type inference which would be an
absolute PITA to implement (not to mention the opposition from the
other core devs):<br>
<br>
=== code begin ===<br>
<br>
Sort(lamba (left, right) as<br>
if left < right then -1<br>
else if left > right then 1<br>
else 0);<br>
<br>
=== code end ===<br>
