jolt-y1zq tail:
- 0-arg (conj) -> [] and 0-arg (conj!) -> a fresh transient vector
- nth sees through a transient (like get/count/contains?)
- irregex \p{...}/\P{...} property classes translate to the seed's ASCII char
classes (regex.ss): \p{L} -> [a-zA-Z] + non-ASCII codepoints (the seed counts
UTF-8 high bytes as letters), \p{N} -> [0-9], \p{Ps} -> [([{], etc. The
translator tracks [...] nesting so a \p{} inside a class emits its content, not
a nested class.
Two pre-existing bugs found and filed (tracked, not replicated):
- jolt-x0os: the Chez emitter mangles non-ASCII string literals into invalid Chez
hex escapes (so p{L} utf-8 crashes on the input string, not the regex).
- jolt-ea9k: the seed's transient assoc! accepts odd args and assigns nil to the
trailing key (non-Clojure; plain assoc throws). The Chez host throws
(Clojure-correct); the 4 spec rows encoding the leniency are flagged in
transients-spec.janet pending the seed fix.
Parity 1493 -> 1506/2497, 0 new divergences. emit-test 291/291.
