Overview

Hash wrapper

The hash wrapper does intermediate calculations of nested lambdas in the specified context as they are encountered

end

Instance Method Details

#[](k) ⇒ Object

Index operator

Performs intermediate transformation of value if needed (if value is a lambda) and returns it wrapping into Definition instance with the same context if needed (if value is a map)
