However, for `class` file parsing, currently the efficient way to check if a constant pool entry matches a desired descriptor is via unrolling them back to strings. However, string unrolling is ugly, and often times confusing, such as internal names versus field descriptors.

This is no less efficient as checking raw string equality, avoids exceptional failure behaviors of conversion to symbolic descriptors, and avoids potential programmer errors stemming from raw string handling.
