// For the purpose of parsing bazel module files in Renovate, we consider a rule
// to be any "direct function application". For example:
//
//     bazel_dep(name = "platforms", version = "0.0.11")
//     ^^^^^^^^^ --> the "rule"
//
// In bazel, rules have typically a more narrow definition. However:
// - They are syntactically indistinguishable from, say, macros.
// - In informal speech, "rule" is often used as umbrella term.
