Guide should cover use of {} around implicit argument hashes

[meagar]

Given this function...

def my_method(user, options = {})
end

All of the following are valid, but which is preferred?

1. my_method x, name: "John", age: 45
2. my_method x, { name: "John", age: 45 }
3. my_method(x, name: "John", age: 45)
4. my_method(x, { name: "John", age: 45 })

I would typically use 1 for a DSL like validates :name, presence: true (the guide already makes allowances for omitting () for DSLs) and 3 for other Ruby code.

Can the guide be updated to explicitly address this question?

+1 but one thing to be aware is multiple hash arguments

def my_method(user, options = {}, html_options = {})

Welp, didn't realize that push -fing in my own repo would repeatedly tag this issue...

I've opened a pull request that may satisfactorily address the issue: #226

Apologies for all the noise in here.
