Streams are typically used in a reduce-like fashion (with a Collector at the end) rather than as seq / iterable. Perhaps extending CollReduce to Stream could be useful

is there a good reason for Var to have an internal dynamic attribute instead of using metadata the way the macro and private flags work?

it's faster to check

isn't that just compile time?

and the metadata came after the attribute

so probably just historical

I remember for some time there could be a mismatch between the attribute and metadata too

I feel like you could argue that having the metadata present is fairly misleading if it doesn't actually have any effect

i think raynes had a patch that made them sync

raynes :(

oh it's still open https://dev.clojure.org/jira/browse/CLJ-859

okay well at least it's been talked about

maybe I'm misremembering things a bit

as far as I remember, for some time there was just setDynamic, and dynamic vars had to be earmuffed -- then the :dynamic metadata was added

but it's been too many years and this is off the top of my head

you can at least still have a mismatch, I just verified that

if I alter-meta! something to add/remove the ^:dynamic flag, it has no effect on the result of .isDynamic

I feel like the cleanest thing is to remove the internal flag altogether, but I'm not a dentist

yeah I agree
