puts, p! methods raise compile error when omit the parenthesis

[TsumiNa]

Do something like this will get a compile error. https://play.crystal-lang.org/#/r/4s6z

p {1, 2}

#=> Syntax error in eval:1: unexpected token: ,Syntax error

Use parenthesis can fix it

p ({1, 2})

#=> {1, 2}

I'm not sure, but seems like a bug.

No, this is how the language works. { after an identifier means passing a block to a method.
