Hi group.
I've tested the following:
irb(main):001:0> def foo
irb(main):002:1> 1,2
irb(main):003:1> end
SyntaxError: compile error
(irb):2: parse error, unexpected ',', expecting kEND
1,2
^
from (irb):3
from :0
irb(main):004:0> def foo
irb(main):005:1> return 1,2
irb(main):006:1> end
=> nil
irb(main):007:0> a,b = foo
=> [1, 2]
irb(main):008:0> a
=> 1
irb(main):009:0> b
=> 2
irb(main):010:0>
So, the bottom line is "1,2" simply fails, but "return 1,2" succeeds.
However, as you know,
def bar
1
end
does return 1.
Why does 1,2 fail? Is there any reason?
Thank for your time.
Sincerely,
