hey all,
I'm hesitant to ask these questions (because they are so simple) but after a
15 minute search through the docs I'm getting nowhere, so here goes:
1) what's the easiest way to generate a list of elements? ie:
'a' .. 'h' == { a,b,c,d,e,f,g,h }
2) Is there a quick way to check whether an element is in a set?
if ('a' == (any('a','b','c','d')) { print "a is in a,b,c,d"; }
The first one I see could possibly be done by 'Array', but I don't see how -
the '#' refers to the generation of numbers, but there seems to be no
corresponding 'letter' symbol.
As for #2, the easiest way would be through an overloading of the '==' operator,
but again, that doesn't seem to work..
Thanks much for any help,
Ed
