defmacro compile time STDOUT generates Dart code

[pfeodrippe]

This one was a little hard to understand what was going on.

If I print something (e.g. with println) inside a defmacro (and the macro compilation is for a deftype (but it may occur for other cases)), the STDOUT goes to the generated code.

(ns example)

(defmacro instance?
  []
  (println '(1 + 4)))

(deftype SciVar []
  Object
  (toString [_]
    (not (instance?))))

throws

✗ dart run

Building package executable...
Failed to build dartapp:dartapp:
lib/cljd-out/quickstart/helloworld.dart:16:1: Error: Expected an identifier, but got '('.
Try inserting an identifier before '('.
(1 + 4)
^

The generated code is something like

... imports ...

// BEGIN SciVar
class SciVar extends dc.Object {

const SciVar():super();
(1 + 4)     // <-- _O_ !!!!!!!!!!!!!!!!!!!!!

dc.String toString(){
return true;
}
}

// END SciVar

// BEGIN instance?
dc.dynamic instance$QMARK_(dc.dynamic $AMPERSAND_form$1, dc.dynamic $AMPERSAND_env$1, ){
final dc.List<dc.dynamic> fl$1=(dc.List<dc.dynamic>.filled(3, 1, ));
fl$1[1]=(Upfddlcoc_core.symbol.$_invoke$2(null, "+", ));
fl$1[2]=4;
final Upfddlcoc_core.PersistentList $1=Upfddlcoc_core.$_list_lit(fl$1, );
return (Upfddlcoc_core.println.$_invoke$1($1, ));
}

// END instance?
