Overview

Generates overloads for methods that accept a single block argument. Those methods are ambiguous because Crystal does not permit overloading through different type restrictions on the block; this processor rectifies this by requiring each overload to also specify the types of the block parameters. For example, the following code

def f(& : Int32 ->)
end

def f(& : Bool ->)
end

def f(& : Int32, Bool ->)
end

is transformed into

def f(_type1_ : Int32.class, & : Int32 ->)
end

def f(_type1_ : Bool.class, & : Bool ->)
end

def f(_type1_ : Int32.class, _type2_ : Bool.class, & : Int32, Bool ->)
end

Unambiguous methods that accept block arguments are unaffected.
