I strongly agree with this.  'specific' IMHO, has no semantic value and
I'd rather just leave the only-sometimes-wrong 'functions' than convert
to something that obscures the meaning always.

My preference would be to use 'symbols'.  I tried to come up with something
but 'symbols' is better than anything I came up with.

Agreed on these two points as well.

Just adding my 2 cents.
