If I want to supply the context to eval-str, I must also specify an error-handler expression: (eval-str str expr ctx)
In this case, can error-handler to have access to the error-value, returned by evaluator?
Because in this syntax using (catch .... 'value) technique becames impossible.
Possible, can expr take one parameter, that is error-value?
Oh, found!
(error-text) does that :-)
