+The `loadfile()` function operates similar to `loadstring()` but reads the
+input to compile from the specified file path instead.
+
+It compiles the given file name into a ucode program and returns the resulting
+entry function.
+
+Throws an exception on compilation or file i/o failure.
+
+Returns the compiled program entry function.
