Re: Does anybody use < to compare lookup keys?

Does anybody use < to compare lookup keys?

Hi Nicolas,

Probably everybody.

<list of associations> asSortedArray

for example.

The problem is at the String >>#< level

both
#a < 1
and
#a < #1
cause errors.

The argument needs to be treated more polymorphicly
(adapt to string and send type stuff ) and this ought
be a mantis item.

Cheers.

Hth,

Yours in curiosity and service, -Jerome Peace
