An eval operation with source form tracking.
Evaluates some code within the dynamic context defined by a map of
bindings, as per
clojure.main/repl to drive the evaluation of :code in a second map
argument (a string), which may also optionally specify a :ns (resolved via
find-ns). The map MUST contain a Transport implementation in :transport;
expression results and errors will be sent via that Transport.
Returns the dynamic scope that remains after evaluating all expressions in :code.
It is assumed that
bindings already contains useful/appropriate entries
for all vars indicated by
Evaluation middleware that supports interrupts and tracking of source forms. Returns a handler that supports "eval" and "interrupt" :op-erations that delegates to the given handler otherwise.
Middleware that notes and allows query of source forms.
