Know your auto-assigning variables!

Jolf has many ways to "auto assign" variables. The standard one is γ, which takes the value of the next expression. Β is the same thing, but converts the next expression to a number.

Also, ζ (zeta) is a variable initialized to -1/12 (guess why), and can be re-assigned with Ζ (Zeta).

For example, let's say you want to compare I (the input string) to an operation over itself. For now, let's see if I + I = reverse(I + I). This is written as, conventionally:

=+II_+II


But this can be golfed down to:

=γ+II_γ
