The symbolic constants API (`java.lang.constant`) was designed, in part, to provide bytecode parsing and generation APIs with a validated, common, symbolic form for constants in Java class files.

There is an easy way to create a `ClassDesc` from a binary name (`ClassDesc::of`) or a field descriptor (`ClassDesc::ofDescriptor`) but not from an internal name. But, the internal name is common in low-level bytecode-manipulation code.

There should be a `ClassDesc::ofInternalName` that creates a `ClassDesc` from an internal name.
