Aha... I agree that's a bit weird. Perhaps lines like these:<div><br></div><div>y => int z;</div><div><br></div><div>are seen as an initialization of z, where y can be taken from the outer scope, and not treated the same as</div>
<div><br></div><div>int z;</div><div>y=> z;</div><div><br></div><div>/Stefan<br><br><div class="gmail_quote">On Wed, Apr 22, 2009 at 10:19 PM, Hans Aberg <span dir="ltr"><<a href="mailto:haberg@math.su.se">haberg@math.su.se</a>></span> wrote:<br>

Compilers can't always be expected to understand every kind of error, and that error message isn't the worst I've seen :) Still, if the opportunity os there to change it to something better, now harm done. The situation can be translated to this:<br>
<br>
int x;<br>
1 => x[1];<br>
<br>
which gives the same subscript error message. Hans's code is otherwise without problems - ChucK allows (like many other languages) to reuse a variable identifier in a new block, so x can be redeclared as an int in the inner while loop, overshadowing the outer x which is an array.<br>

The problem is really that 'chuck' accepts<div class="im"><br>
x[msg.which] => int x;<br></div>
Then when a line after that is added<div class="im"><br>
x[msg.which] => int x0;<br></div>
it complains about this line, giving that cryptic message, despite the fact that it is correct.<br>
<br>
When the first line is accepted, that gives the impression that this name overloading is legal, though it differs from C++. Thus I started to use it.<br>
<br>
Chuck needs to make up its mind: is this name overloading legal or not. If it is not, it should always be rejected.<div><div></div><div class="h5"><br>
