More questions on the "-pe" one-liner flag: in conjunction with s/// and tr///

Hello, Can anyone answer why--in a one-liner using the "-pe" flag--the s/// and tr/// functions do not require a "." (dot) preceding the function call? Clearly adding a "." (dot) before either one results in an error (code below). Also, adding a ".=" (dot-equals) sign before the either the s/// or
