Crystal Language That Aims at C Performance with Ruby Syntax Releases 1.0

  def fibonacci(n : UInt64)
    return 1_u64 if n <= 1
    fib(n - 1) + fib(n - 2)
  end
 
  puts fib(46)

Am I reading this wrong or should that start with `def fib(n : UInt64)`?

This could be a killer feature - smart inferred function name.

As a joke in college, I came up with the idea of a language that used fuzzy-matching to find the variable/function name with the closest match to the identifier used if an exact match wasn't found. This has the "fun" property where as long as a single variable is in scope, there are no undefined variable errors :)

This seems like a super fun idea

Until someone adds a method called fib (staying with the example of the thread) doing something completely different.

Dynamic method swapout during recursion! Who doesn't want that feature?
