3 cheers to the folks that think APIs make a good toy box but not necessarily 
a good tool box. There are obviously good solid APIs but there is also a lot 
more that are mere ego trips. I reminder of the PL/1 language. It was good, 
too good and went into disuse because it was too difficult to get off the 
ground 
for the everyday folks. I am also reminded that a study done for Admiral 
Grace Hopper show that 94% of all the code that was generated for the Navy up 
to 
about 1970 used only 10 of the 600 plus instructions on the s/360. We now run 
on RISC machines because they could be made to run faster and more reliably 
then they older CISC predecessors.
