, which
increments an atomic operand.
Produces

Tall form
.+ p
Wide form
.+(p)
Irregular form
+(p)
Examples

~zod/try=> +(2)

In the most straightforward case .+
increments its operand.
~zod/try=> +(~zod)
1
/~zod/try=> `@`~zod
0
/~zod/try=> `@`'a'
97
~zod/try=> +('a')
98
/~zod/try=> `@`0xff
255
~zod/try=> +(0xff)
256
~zod/try=> +(41)
42
When passed a non-atomic odored atoms .+
down-casts to an atom.
~zod/try=> +([1 2])
! type-fail
! exit
Passing an operand that cannot be directly down-cast to an atom produces a type-fail.
