I guess the problem I had is that the optional typing moniker seems
misleading since it forces you to annotate vars. I had visions of gradually

How about annotating clojure.core API. Is it needed, provided, optional?

I see optional typing as the opposite of mandatory typing. You don't need
to pass a type checker to get a program semantics.
Typed Clojure offers a particular flavour of optional typing: gradual
typing. My interpretation of gradual typing is some of your code is
rigorously statically typed, some
Hi,
Roughly 1/3 of clojure.core is annotated and comes included with
core.typed. They are unchecked annotations.
https://github.com/clojure/core.typed/blob/master/src/main/clojure/clojure/core/typed/base_env.clj#L658
You can lookup types via cf at the REPL.
(clojure.core.typed/cf +)
;= (Fn
Also you can add missing annotations via ann.
(ann ^:no-check clojure.core/+ )
Core vars observe the same rules as all vars: they must be annotated.
Thanks,
Ambrose

Hey,
this sounds interesting. I just tried it on my project but it seems to be
missing several keywords in the constants_table.js.
Dumb example: the code tries to use cljs.core.constant$keyword$1064 , which
does not exist.
Will try to investigate, just a heads up.

Functions don't really have names. A function may be bound to a var,

core.typed is not a compiler, it's a type annotation/checker implemented
as a library.

I certainly like that better than the binding solution, especially if
hotspot can potentially inline the functions. It still tricky to do
that in a macro, especially when the code to be evaled depends on the
current lexical scope, but I can maybe work around that. Thanks.

With Clojure the lines blur between compile time and runtime.
The clearest way to put it is that type checking is explicitly called at
the REPL or in a unit test. Usually this is done during development
iterations or testing time.
Re: performance improvements: Michael is correct. Interestingly
If you can do that, why not return the literal representation of the type
hinted function?
For the repl you could provide a function that interns the type-hinted
function into the namespace by evaluating the literal representation first.
From there it's easy to provide something like
I don't think it would be possible to reconstruct the original forms in
general, you would need to reverse macroexpansion to provide a form that
has at least a passing familiarity with the original form. Otherwise you
would get fully macroexpanded forms.
That's a lot of work!

Those forms won't be in the namespace you're evaluating?
