Hi,
I would like to use the EOL iterate operation on a collection of objects
of type OrderedSet, however I'm having difficulty understanding the
syntax of the operation.
e.g.
var msbs : OrderedSet(Integer) := self.getFields().collect(field |
field.msb).asOrderedSet();
var maxMsb : Integer := 0;
msb := msbs.iterate(msb : Integer; x : Integer = 0 | msb.max(x));
The iterate operation fails to parse, although I think this conforms to
the format identified in the Epsilon book. This form also fails to parse:
msb := msbs.iterate(msb; x=0 | msb.max(x));
I'm obviously doing something daft, can someone correct my mistake?
Regards
Chris

Hi Chris,
Alas, this seems to be a bug. Could you please file a bug report and use
"for" loops instead of "iterate" until we get this fixed?
Cheers,
Dimitris
