Do you mean handwritten, or just a printed hardcopy? If it was handwritten, cue loading up my handwriting as a font and typing it anyway. ;) A couple of my programming instructors use a build system that compiles your code with three different compilers, and runs it with various tests and diffs the output with a master copy (or sometimes stress-testing and tracking memory/time/probe counts). One of them also ran valgrind on submissions. So you'd get your "accuracy score" on the same day or so as the programs were due, then the teacher/TAs would grade the source and dock points for bugs not found in the test, supreme ugliness, etc.
