It is aggressive in its unicode support. You want to use vulgar fractions? Or Mayan numerals? They'll work. You want to use mathematical notation like ∈? It works.
You can literally do this:
`my $var = ⅒ + 2 + Ⅻ;`
I can't include an example here because VC News strips out math.
∂ₓₙ = [(₁ ⊗ ʹ) (₂ ⊗ ʹ) ( ⊗ ₁) ( ⊗ ₂)]
And last I checked, BPL is in the same boat.
