Ah thanks James, I missed the pending nil. The actual value is still nil
indeed:
user=> (def m (re-matches #".*(foo\.gif).*" "foo.gif\n"))
"foo.gif\n"#'user/m
user=> m
nil
Not sure what would be the cause here then, but the random printing of the
second argument of re-matches also happens when I evaluate an arbitrary
function after the exception
PatternSyntaxException Unmatched closing ')' near index 13
.*(foo\.gif).*)
^ java.util.regex.Pattern.error (Pattern.java:1924)
RuntimeException Unmatched delimiter: ) clojure.lang.Util.runtimeException
(Util.java:221)
user=> (list 1 2)
"foo.gif\n"(1 2)
cider doesn't have this problem either it seems
