Your task is to write a program or function that outputs the first character of its source code, then the second, then the third... each time it is run.
For example, if your program was
foo in language
bar in file
baz.bar, then you should get output similar to this:
λ bar baz.bar f λ bar baz.bar o λ bar baz.bar o
Your program can do anything once its done printing its source code in this fashion. You may modify the source code for the file, but remember that the source code to be printed is the original source code.
This is a code-golf, so the shortest program in bytes wins.
