Function EvalBuiltIn

Evaluates meta[property] with variables

• Compiles meta[property] if it wasn't compiled already (also with cache check)
• Evaluates the resulting function with the merge of meta.scope and variables

Example

meta: {
  fn: 'x + 3',
  scope: { y: 3 }
}
property: 'fn'
variables:  { x: 3 }

Returns

The builtIn evaluator returns a number, the interval evaluator an array
