• Wrapper, register and debug moved to varname.helpers
• Argument caller changed to frame across all APIs
• ignore accepting module, filename, function, (function, num_decorators), (module, qualname) and (filename, qualname)

• inject (Use helpers.regiester instead)
• inject_varname (Use helpers.regiester instead)
• namedtuple

• Arguments frame and ignore to Wrapper
• helpers.register as a decorator for functions
