Can there be subscript/superscript support? Maybe something like: a_0 » a₀ a_n » aₙ a^2 » a² a^n » aⁿ In the case of exponents becoming superscript, this can be an option, and you could maybe have the "subscript character" be something other than "_" to avoid potential issues with variable names. But with the addition of subscript, I feel it could lead the way to adding support for defining arithmetic/geometric sequences. (and maybe other functions in future?) Example of a sequence: aₙ = a₁ + 5n, a₁ = 3 | a₁ | 3 a₄ | 23 a₄ == 3 + (5 * 4) | true If you want to define a range where the sequence works, you could do something like desmos: aₙ = a₁ + 5n, a₁ = 3 {1 <= n <= 5} | a₁ | 3 a₄ | 23 a₄ == 3 + (5 * 4) | true a₀ | RangeError a₅ | 28 a₆ | RangeError // some error thrown saying n is outside designated valid range The "item position" in a sequence ("n" in the above examples) can only be an integer, so an error could be thrown there too: aₙ = a₁ + 5n, a₁ = 3 {1 <= n <= 5} | a₁ | 3 a₄ | 23 a₄ == 3 + (5 * 4) | true a_3.5 | ValueError // pretend the 3.5 is subscript, as it would be from above.
