Loading these libs via require worked (load-ns-source interprets, macros
expand lazily) but the same code inlined by uberscript routes through
eval-toplevel and compiled, surfacing four gaps:
- a ^{:map} metadata def name reads as (def (with-meta name m) v); the
analyzer died extracting the name (config.core's defonce env). It now
throws uncompilable so the interpreter, which handles it, takes over.
- declare was a no-op, so a compiled forward reference to a declared
name that collides with a janet root binding bound to the host fn
(selmer.parser's (declare parse) compiled to janet's 1-arg parse).
declare now expands to no-init defs, the interpreter interns them,
and the analyzer routes no-init def to the interpreter.
- class? was missing (selmer.util's exception macro calls it at
expansion time). Always false, like ratio? — no Class objects here.
- require of an unlocatable namespace silently left an empty ns behind,
deferring the failure to an unresolved symbol far from the cause. It
now throws like Clojure's FileNotFoundException. Namespaces entered
in-session count as loaded (Clojure puts them in *loaded-libs*), and
the SCI bootstrap opts out via :lenient-require? since its
clj-targeted requires can't all exist on this host.
