type-analyze

Statically analyze types through comments

// foo : Number -> Number
function foo (x) {
  return x + 1
}
 
foo('Hello')
// TypeError: foo('Hello') doesnt match Number -> Number

This module is a work in progress:

• [ ]: Wildcards in type signature using *
• [ ]: Infers types of expressions (in functions and identifiers)
• [ ]: Loads identifier type signature
• [ ]: Checks identifier types
• [ ]: Proper support for scopes
