This form now emits valid JS. However, using DOLIST instead
of LOOP here causes a syntax error:
(ps (lambda ()
(cond ((foo? x) (dolist (y x) (foo y)))
((bar? x) x)
(t t))))
=>
"function () {
if (foowhat(x)) {
return for (var y = null, _js_idx1288 = 0; _js_idx1288 < x.length; _js_i\
dx1288 += 1) {
y = x[_js_idx1288];
foo(y);
};
} else if (barwhat(x)) {
return x;
} else {
return true;
};
};"
Here is some more curious DOLIST behavior:
SKYSHEET> (ps (lambda () (dolist (arg args) (foo arg))))
"function () {
for (var arg = null, _js_idx1289 = 0; _js_idx1289 < args.length; _js_idx1289\
+= 1) {
arg = args[_js_idx1289];
foo(arg);
};
};"
SKYSHEET> (ps (lambda () (let ((x y)) (dolist (arg args) (foo arg)))))
"function () {
var x = y;
return for (var arg = null, _js_idx1290 = 0; _js_idx1290 < args.length; _js_\
idx1290 += 1) {
arg = args[_js_idx1290];
foo(arg);
};
};"
