1//! Batteries-included proc-macro utils
2//!
3//! This re-exports the common libraries - `syn`, `quote`, and `proc-macro2`,
4//! that you need to work with proc-macros, as well as utilities
5//! to interop between them.
6//!
7//! # Re-exports
8//! Most of `quote`, `proc_macro`, and `proc_macro2` are re-exported,
9//! and they can be used with the `pm::` prefix. Types that have the same
10//! name in `proc_macro` and `proc_macro2` are suffixed with `2` in
11//! the `proc_macro2` export.
12//!
13//! Types from `syn` can be used as with `syn::` prefix, by adding
14//! the prelude import `use pm::pre::*`.
