macro bug, seems to work once and then get stuck #223

Closed ldemailly closed 2 months ago

ldemailly commented 2 months ago 

unless(5 > 11, println("macro test 1: lower ok"), println("BUG: not lower"))

unless(10 > 5, println("BUG: not greater"), println("macro test 2: greater")) // should output "macro test: greater" and not again "lower ok"

actually currently prints

macro test: lower ok
macro test: lower ok

also unable to get 

NoErr = macro(expr,a,b) {
    quote(
        r = catch(unquote(expr))
        if r.err {
            error("unexpected error:", r.value)
            unquote(a)
        } else {
            unquote(b)
        }
    )
}

to work... complains about expr being unknown...
