A Workaround To A Near Miss Part II

Published 04 November 2008 by Farrel

Following on from my previous article here’s a slightly neater way to combine Proc#=== and Symbol#to_proc. No special functions required.

1 case number
2 when lambda( &:even? )
3   puts "Even!"
4 when lambda( &:odd? )
5   puts "Odd!"
6 when lambda( &:zero? )
7   puts "Zero!"
8 end
