Bug #11528

closed

Possible parsing bug. Possibly just confusing.

Description

Not sure if this is intentional behavior but I found it confusing:

code:

def render(args)
  p args.to_a
end

print 'functionally (without parentheses): '
render "foobar".length\
        .to_s(2)\
        .split('')\
        .map do |d|
  {digit: d}
end

print 'functionally (with parentheses): '
render("foobar".length\
        .to_s(2)\
        .split('')\
        .map do |d|
         {digit: d}
       end)

print 'with an intermediate variable: '
data = "foobar".length\
        .to_s(2)\
        .split('')\
        .map do |d|
  {digit: d}
end
render data

output:

functionally (without parentheses): ["1", "1", "0"]
functionally (with parentheses): [{:digit=>"1"}, {:digit=>"1"}, {:digit=>"0"}]
with an intermediate variable: [{:digit=>"1"}, {:digit=>"1"}, {:digit=>"0"}]
