There's a problem, though: the str-utils2/ltrim function seems to be

It mostly boils down to using the Maybe monad to avoid giant nested if-

Some of the most common uses for monads have pre-existing mechanisms
with Clojure to handle them, e.g.:
sequence monad (for)
state monad (Clojure has many stateful mechansisms)

and use something like when-let to process it)

Hi All,
So, I've been doing some experimentation in order to better understand

these four calls:

java.lang.IllegalArgumentException: Wrong number of args (0) passed
to: Symbol (NO_SOURCE_FILE:0
If I could hazard a guess, it has to do with symbol lookup in maps.
Try the following:
('foo {'foo 1})
('foo {'bloo 1} 4)
when you do ('foo 1), it can't find foo in 1 (because it isn't there,
and 1 isn't even a map), so it returns nil. If you do ('foo 1 2),
you've just provided a default value,

I'm not 100% sure but this is a side effect of the property that symbols
can be used as functions that find themselves on maps.
For instance:
(def m {'a 1 'b 2 'c 3})
('a m)
;=> 1
('b m)
;=> 2
and, when the symbols is not found, we have:
('d m)
;=> nilurn
('d m :nono)
;=> :nono
So a symbol is

I certainly won't try too hard either. I'm not questioning here
whether it is immediately practicable to implement (maybe not, and in
case a very long discussion) but is it potentially useful?
Putting that kind of logic in IMatchLookup doesn't make much sense to me:
I'm not sure about the following syntax, but something like this could be
done w/o interfering with IMatchLookup.
(match [obj]
[({:mice 4} :type cat)] ...
[({:cats 4} :type dog)] ...
[({:cats 4} :type :not [cat dog]]
