Allow to evaluate an expression in printer

[mrkam2]

It would be great if I was possible to evaluate and print a custom expression using the data available in a printer position. So the following two scenarios are possible:

• Evaluate an expression over several values in a given point of the code. Such as (+ a b).
• Modify the expression returned by a given form. For example, (select-keys % [:a :b]).

I think this is a nice thing to have.

Evaluate an expression over several values in a given point of the code. Such as (+ a b).

this is tricky to implement if possible at all.

Modify the expression returned by a given form. For example, (select-keys % [:a :b])

☝🏼 this one is imo the way to go
