Sorbet, the Ruby type checker, uses *.rbi files (Ruby interface files) to
provide optional type annotations without touching the source *.rb files. They
act similar to *.h files in C/C++ and *.d.ts files in TypeScript.
The syntax of RBI files is a subset of Ruby syntax, so ever line of an RBI file
is effectively a line of Ruby code.
