Lazy evaluating with Enumerable#any?

Most of us know this:

1 2 3 4 5 6 7 8

class Awesome def self.m1 ; true ; end def self.m2 ; raise Exception ; end end # Case 1: Awesome.m1 or Awesome.m2 # >> no error thrown

For some of us who likes Enumerable#any?, this won't work:

1 2 3

# Case 2: [Awesome.m1, Awesome.m2].any? # >> error thrown

That is because :m1 & :m2 are already evaluated before calling Enumerable#any?, to have lazy evaluation, we can do this:

1 2 3

# Case 3: [:m1, :m2].any?{|m| Awesome.send(m) } # >> no error thrown

For the perversive ones:

1 2 3

# Case 4: Awesome.instance_exec { [:m1, :m2].any?{|m| send(m) } } # >> no error thrown
