+/**
+ * Parse a path string into an array of path segments.
+ *
+ * Square bracket notation `a[b]` may be used to "escape" dots that would otherwise be interpreted as path separators.
+ *
+ * Example:
+ * a -> ['a']
+ * a.b.c -> ['a', 'b', 'c']
+ * a[b].c -> ['a', 'b', 'c']
+ * a[b.c].e.f -> ['a', 'b.c', 'e', 'f']
+ * a[b][c][d] -> ['a', 'b', 'c', 'd']
+ *
+ * @param {string|string[]} path
