# how does lexical scoping work for lambdas?

x = 5

p = lambda {
 puts x
 x += 100 # can modify x in enclosing scope
 puts x
 puts 'end of p'
}

def gimme
 x = 10
 print 'In gimme, x is '
 puts x
 yield
 puts "You're welcome."
 print 'In gimme, x is '
 puts x
end

gimme &p # use '&' to turn a lambda into a block
print 'In main, x is '
puts x
