Just in case I'm not the only ignorant person who didn't immediately
know what "syn" is and why we might want 57,000 lines of it in the
kernel... :)

Syn is a parsing library for parsing a stream of Rust tokens into a
syntax tree of Rust source code.

Currently this library is geared toward use in Rust procedural
macros, but contains some APIs that may be useful more generally
