Did you do generics?  That and the run time, which had some real-time
bits to it (*IIRC*, it's been a long time), as well as the cross
object code type checking, would have been real bears.

Like many things, the first 90% is easy, the second 90% is hard. :-)

You are undoubtedly better than you give yourself credit for, even
if there were people who could run circles around you.  I learned
a long time ago, that no matter how good you are, there's always
someone better than you at something. I decided long ago to not
try to compete with Superman.

And it makes it much less fun to be out in the working world. :-(
