decl_pos and decl_olean for current file

Stream: Is there code for X?

[Tsuru]

environment.decl_pos and environment.decl_olean can be used for imported files only, and return none for declarations in the current file.
Is there any function that can get the position of declarations in the current file (like decl_pos)? Also, is there any function that can get the path of the current file (like decl_olean)?
