Example

var fulcon = require('fulcon');
 
function original(a, b, c)
{
  return 42 + a + b + c;
}
 
assert.strictEqual(original.length, 3, 'signature of the original function has 3 arguments');
assert.strictEqual(original(1, 2, 3), 48, 'original function returns 48');
 
var cloned = fulcon(original);
 
assert.notStrictEqual(original, cloned, 'original and cloned functions are not the same function');
 
assert.strictEqual(cloned.length, 3, 'signature of the cloned function has 3 arguments');
assert.strictEqual(cloned(1, 2, 3), 48, 'cloned function returns 48');

Note: Beware of functions with side-effects! Cloned function calls original function under the hood, so it has same side-effects for better or for worst. Check test.js for details.
