CoffeeScript for formulation of validation rules

Issue description

CoffeeScript seems the better choice (than JavaScript) for formulation of validation rules of compound constraints.

Developer comments

The evaluation has two implicitly defined symbols: [%fail = new ValidationError()%] [%blame = function () { return new ValidationError(arguments) } %]

Rejection comment

Cool, but no longer relevant. JavaScript is good enough.

Use cases

[%(start, end) -> fail if start and end and start >= end %]

[%(flag, comment) -> fail if flag is no and not comment%]

[%(pictures, comment) -> blame pictures, comment if pictures.length < 4 and not comment %]
