I would like to discuss the best way to indicate intent for
decorated variables.

Case 1:
f with something on top of it, such as:
bar, tilde, hat
(Those are not the official Unicode names.)

Typically these have a meaning, and commonly they are pronounced
"f bar", "f tilde", "f hat".

Ideally I would want it pronounced "f hat" and provide the reader
a way to know that it means "Fourier transform of f". But, I would
not want the reader to hear "Fourier transform of f" every time.
(So, I am willing to sacrifice the meaning in order to get the
usual pronunciation.)

Case 2:
f with a superscript that is a symbol, such as:
*, ', + .

Again, there may be a meaning, but commonly the pronunciation
would be "f star", "f prime", "f plus". It is okay with me if
AT says "f sup star", etc.

It would help if the default pronunciation is as described above.
Then a property could be used to indicate the meaning and not
change pronunciation.
