Anybody know if there's an easy way to accomplish the equivalent of
this:

[1..20, 30..46].each{|n|
# n = 1,2,3,4,5..30, 31, 32
}

?

Thanks!

Will this work:
[1..20,30..46].each{|r| r.each {|n| p n}}

Only thing that comes to mind for me is

r1 = 1..20
r2 = 30..46
(r1.to_a + r2.to_a).each{|n| puts n}

Probably not the best solution, but works...

Adding parentheses may make it a little clearer:
[(1..20),(30..46)].each{|r| r.each {|n| p n}}

Yeah that works.

I guess if I need individual values in there (like 25) I can do

[1..20, 25..25, 30..46].each{|r| r.each {|n| p n}}

So that'll work.
Thanks.
