brings clojure/midjes meta-constants (https://github.com/marick/Midje/wiki/Metaconstants) to javascript

a meta-constant replaces this testing pattern:

expect(identity(42)).toBe(42);

with

expect(identity(_$_`a-number`)).toBe(_$_`a-number`);

Although this is longer, it makes clear that the value is only threaded through the function under test and any (number) will do.

meta-constants only provide identity. If your function under test requires more than that from a value, you need a real value

The template functionality isn't used used?!

Answer:

• syntactical difference
• template functionality may become useful later...
