1//! [`quote`] using only one [`TokenStream`](proc_macro2::TokenStream).
2//!
3//! this crate provide a [`quote`] inspired macro [`chunk!`] that builds [`TokenStream`](proc_macro2::TokenStream)s though direct appending not object composition.
4//!
5//! it support all [`quote`] features except `macro_rules` inspired repetetion, and add additional features like control flow and do blocks.
