Ruby block variable scope within/out the method -
i following different results:
test 1:
def myblock x = 1 y = 1 yield(x) [x, y] end myblock |x| y = 10 end # => [1,1]
test 2:
x = 1 y = 1 1.upto(2) |x| y = 20 end [x,y] # => [1,20]
variables created outside block available in block. why so?
that how scope of local variable defined. local variable can percolate block, not method definition.
