That's how Janus/Ada worked for its early life. (Strictly speaking, it was 
the elaboration of a package body that was the main subprogram, typically 
that would have just been a call.) Eventually, we had to change it to a 
subprogram in order to run the ACVC (now ACATS). For a long time, there was 
an option to have a package be the main, but we got rid of it at some point 
when it was causing some bugs.
