Domain of inverse(abs2)

[jariji]

Should this be allowed?

using Accessors
julia> modify(-2, abs2) do x
           x + 1
       end
2.23606797749979

julia> inverse(abs2)
sqrt (generic function with 19 methods)

This issue is similar to #8.

I get

julia> using Accessors, InverseFunctions

julia> modify(-2, abs2) do x
           x + 1
       end
ERROR: This should be unreachable. You probably need to overload
`Accessors.set(obj, ::typeof(abs2), val)

and

julia> inverse(abs2)
NoInverse{typeof(abs2)}(abs2)

Huh, I'm not sure what happened. I must've changed something in my repl beforehand. Sorry for the noise.

No worries!
