r4: for comprehensions for Rust
This package provides the
iterate! macro, which builds for comprehensions out
of nested flat-map operations. If you're familiar with Python's list
comprehensions or Scala's for statement, the syntax should be familiar.
See rustdocs for usage, examples, and a more detailed description of the macro's internals.
- Examine overhead introduced by nesting closures instead of using naked loops.
- ?Figure out how to avoid moving values we don't have to.
- ?Figure out how to avoid creating some new iterators unnecessarily.
