You are suggesting that "options require arguments by default" is less
implicit than "options are boolean toggles by default". This is unclear
to me.
As to which default is preferable and less surprising, I prefer the
latter since it matches the conventions in C, bash, Perl, and Ruby. My
understanding is that the former is the default on Python. Perhaps this
is the source of our disagreement?
I do agree that the documentation is not clear enough on this matter; I
will ameliorate this later today.

with-meta calls .withMeta on its argument at runtime, so everything that

What's interesting is that

should be able to work around this by creating the
namespace manually from a namespace that does exist, like the `user` ns:
user=> (create-ns 'my.broken-ns)
The namespace will still be broken, but you should now at least see
compiler errors.

go-loop needs to be a macro to capture the unevaluated let bindings:
(go-loop [i 0] …)
If go-loop were a function, this code would throw an error because i is
undefined.

Overall, it seems to me that you are looking for a better way to
manage implicit parameters¹. However, I imagine a sizable part of this

I find that my desires for a stepping debugger are mostly absent with
Clojure as data is immutable, and the reference types may be monitored

The interface is modelled after clojure.tools.cli¹, but the parser is

I have the call to slam.hound bound to a key sequence in my editor², so
I do not have to suffer a context switch:

There remain a few small problems (and one admittedly large one WRT
macros), but I think automated ns management is a kill

emacs.
My apologies if you've already considered this. If you haven't, I hope
