Operator Usage

Name

|__self>

Description

|__self>
|__selfk>
the multi-line self ket
for anonymous and multi-line functions or multi-line operators, input parameters are bound to their respective multi-line self-ket
where k is a positive integer
this notation is now partially deprecated in favour of bound functions


Examples

-- define an operator, that accesses elements one ket at a time:
op |*> #=>
    sprint["input: "] |__self0>
    sprint["one: "] |__self1>
    |return var>

-- define a function that accesses the entire sequence, instead of ket-wise:
fn (*) #=>
    sprint["input: "] |__self0>
    sprint["one: "] |__self1>
    |return var>


-- now invoke them:
-- noting that op was invoked 3 times, one for each ket in the input, while fn was invoked only once.
sa: op rank split |abc>

    input: |__self0>
    one: |a>
    input: |__self0>
    one: 2|b>
    input: |__self0>
    one: 3|c>
    3|return var>

sa: fn rank split |abc>

    input: |>
    one: |a> + 2|b> + 3|c>
    |return var>
