I think you'll find too many anomalies if FTX supports // and ** directly.
You have to also make sure you don't FTX format text that is not intended to be
FTX formatted. Some examples to consider follow.
For slashes:

I'll be there on 5/30/03 at noon.
You need to put a </TD> tag after the </A> tag.
my $BAR = join "", grep { !m/[\Q$foo\E\s]/ } map { chr($_) } (32..255);
For asterisks:
If you want to do that use: grep -l a*b* *.txt
The correct formula is a * a + b * b = c * c
Some situations may even be ambiguous as to whether they were intended to be
FTX formatted or not.
Even with [] and {} you might have some problems. For example, what would
happen if I wanted this message to use FTX formatting in a reply to your
message? What would your parsing code look like? And do I really need the
headache of having to take the time to make the FTX changes to preserve the
format? What if I don't know I need to do it in subtle situations?
