Feature request - A function for current procedure/function name getter

• Current procedure/function name getter
  > by calling (for example) 'PRO_NAME()'' in a procedure or function like the function 'DATABASE()'
  > to identify each caller function name/identifier

Multiple call hierarchy of prcedure make some custom/user own logs
but need to SPECIFYING the log caller manually but when change the procedure names,
people missing the logic changes which log identifier that caller. I do not think this small tasks really necessory to focus on which makes mistakes and hard to tract the logic hierarchy
