## Feature #7612

closed### Enumerators take a proc

**Description**

If there is already a clean syntax for this, I apologize. I sure could not find it.

class Foo

def initialize

@inst = 18

end

def meth(a, b)

puts "method #{@inst} #{a} #{b}"

end

end

foo = Foo.new

e = %w{a b c}.each_with_index

p1 = Proc.new { |a, b| puts "proc #{a} #{b}" }

m2 = foo.method(:meth)

p2 = m2.to_proc

# Current Syntax possibilities¶

e.each { |a, b| puts "direct #{a} #{b}" }

e.each { |a, b| foo.meth(a, b) }

e.each { |a, b| p1.call(a,b) }

e.each { |a, b| m2.call(a,b) }

e.each { |a, b| p2.call(a,b) }

# Proposed Addition¶

e.each(p1) # same as e.each { |a, b| p1.call(a,b) }

e.each(m2) # same as e.each { |a, b| m2.call(a,b) }

e.each(p2) # same as e.each { |a, b| p2.call(a,b) }

# In the case of a method or lambda, the arguments are checked and possible errors thrown.¶

# In the case of a proc, the proc "tricks" apply¶

To add readability, an "apply_to" method could be added:

e.apply_to(p1)

The extra "each" bothers me since the enumerator already has an "each" associated with it.
