Type Sig(natures) / Annotation

What syntax to use - while still following the "it's just ruby" idea / philosophy / principle?

i try to improve the method sig(nature) / type annotation using the Module.method_added hook "metaprogramming magic". the idea is to drop / kill the duplicate method name, thus:

sig :transfer, [Address, UInt], returns: Bool
def transfer( to:, amount: )
  #...
end

becomes

sig  [Address, UInt], returns: Bool
def transfer( to:, amount: )
  #...
end 

i know method sig(nature) / type annotatation are ugly. not sure if a "string" version is better?

sig '(Address, UInt) => Bool', 
def transfer( to:, amount: )
  #...
end 

#  @sig (Address, UInt) => Bool 
def transfer( to:, amount: )
  #...
end 

maybe this is possible?

def transfer( to: Address, amount: UInt, returns: Bool )
  #...
end

or adding the sig(nature) inline as last parameter?

def transfer( to:, amount:,  sig: '(Address, UInt) => Bool' )
  #...
end

or with unicode magic types / sig(nature) encoded in name itself?

def transfer‹Address_UInt→Bool›( to:, amount: )
  #...
end

your ideas / suggestions here. yes, you can.
