Cute and Efficient Is Definitely Possible

• Compossible, lazily evaluated generators such as map, filter, fold, enumerated ranges and more.
• Easy handling of input and output streams, reading line by line, parsing objects, etc.
• Compact syntax: Choice between * Functional fold(…,map(…,filter(…))) * Piped filter(…) | map(…) | fold(…)
• Zero cost abstractions leveraging C++ templates, no macros involved.
• Easily create new generators and integrate with existing ones.
• Optionally enabled macros to make the syntax even more cute.
