Are unicode function names not supported in dmd?
bool ∩(A, B)(A a, B b){
	return intersect(a, b);
}
Error: character 0x2229 is not a valid token

I won't be terribly disappointed if I can't do this, I really just tried it on a whim, but I thought dmd supported unicode.

Oddly enough bool π(A, B)(A a, B b) { ... } works just fine.

Try Ÿ.
The character I have shown above will work as it is an alphabetic[0] character.

Also visual D seems to recognize its not a valid character and highlights the error which makes me think its known behavior.

Yeah Ÿ and π both work but ∩ does not. I think I found my answer though...
http://dlang.org/spec/lex.html#IdentifierChar
> Identifiers start with a letter, _, or universal alpha, and are followed by any number of letters, _, digits, or universal alphas. Universal alphas are as defined in ISO/IEC 9899:1999(E) Appendix D. (This is the C99 Standard.) Identifiers can be arbitrarily long, and are case sensitive. Identifiers starting with __ (two underscores) are reserved.

Here's a few ANSI characters you can use (and can type with alt-codes):
ª º · Ø ø µ ƒ
I use º pretty often, it makes a nice sigil.

And if you can't remember the alt-codes (I never can) I use compose
keys for the easy stuff ™ © ° and the like and keyboard remapping for
the harder stuff θ μ π and the like..

Personally, I would prefer 'intersect' as a function name over '∩' anytime.

Which benifits does the symbols add?

Sounds like you'd love Java.
x = new BigDecimal("0.1")
x.negate().divide(y).compareTo(z)

who needs symbols? >_>

Well, I wasn't trying to start a language battle, I like D (which maintains a 'union' keyword;-))

I simply see no need for code obfuscation using, possibly, ambiguous symbols.

Your auto 'start-pointing-fingers' reply did not change that.
