Generic language fixes so a host-shim library (jolt-lang/http-client) can carry
clj-http-lite without baking any HTTP/native code into core:
- reader: accept #^ (deprecated metadata reader macro) as ^
- (str pattern) returns the raw regex source, not #"..." — pattern composition
via (re-pattern (str p ...)) now works
- into/conj onto a map merges map items (was (into {} [{:a 1}]) -> {nil nil})
- a Var is callable as its current value (e.g. (wrap #'f) threading a var client)
- core-class reads a :class field off a thrown table, so libraries can throw
typed exceptions whose (class e) is a JVM class name
- compiled catch unwraps the interpreter's :jolt/exception envelope (__unwrap-ex),
so a typed throw keeps its class/message across the interpret/compile boundary
- slurp accepts a byte-array; io/copy is generic over :jolt/input-stream /
:jolt/output-stream stream markers
- instance? gains a registry (__register-instance-check!) for library shim types
- new clojure.test namespace (deftest/is/are/testing/use-fixtures/run-tests with
class-aware thrown?/thrown-with-msg?)
Spec: test/spec/clojure-interop-fixes-spec.janet.
