fake id(x) for better 2sinh method.

[tommy1729]

Hmm this new id(z) also seems in trouble because

id(z) -z goes to 0 for large z ... but stays bounded for small z : so id(z) - z is not entire.

So maybe use a function that grows like exp(x) near the real line and grows like z otherwise ?

Notice if id(z) is not entire , then neither is id(exp(z)) or even id(fakeexp(z)).

Hmm.

Seems really an issue.
