Lets have a closer look at alan's examples: 

if anyone loads an

>effect of ${\bf waffle + \Gamma}$.

One of the major thing we decided is that MC IS NOT FOR MULTILETTER
identifiers.   So this example is no good.

if anyone loads an

for setting chemical formulae, then the <fi>, <ff>, <fl>, <ffi> and <ffl>

Well I have studied chemistry a little, and i could not think where those
would be used. apart from in TEXT.
