in reply to Perl execution
As far as I understand, no object output file is created during compilation of perl code and While running the code , each line is interpreted and executed before proceeding to next line.You understood that wrong.
Perl is neither purely compiled; nor purely interpreted. It is a bit of both and neither.
The perl executive reads the whole program and "compiles" it into an intermediate form, which then gets interpreted. Changing the source of your Perl script from within the program comes too late as your program has already been read in and compiled and it runs now out of its internal represenation which is utterly disconnected from the source text.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
