Subject: Undefined local variable?

Dear All,

Why is there still NameError?

ruby-1.9.2-p0 > l = ->{ h }
 => #<Proc:0x000001009d7eb0@(irb):1 (lambda)> 
ruby-1.9.2-p0 > l.call
NameError: undefined local variable or method `h' for main:Object
	from (irb):1:in `block in irb_binding'
	from (irb):2:in `call'
	from (irb):2
	from /Users/siegfried/.rvm/rubies/ruby-1.9.2-p0/bin/irb:17:in `<main>'
ruby-1.9.2-p0 > h = 1
 => 1 
ruby-1.9.2-p0 > l.call
NameError: undefined local variable or method `h' for main:Object
	from (irb):1:in `block in irb_binding'
	from (irb):4:in `call'
	from (irb):4
	from /Users/siegfried/.rvm/rubies/ruby-1.9.2-p0/bin/irb:17:in `<main>'

Best regards,
