The syntax for defrecord literals and tagged literals is very similar.
user> (defrecord x [y])
user.x
user> #user.x[3]
#user.x{:y 3}
user> #user.x [3]
RuntimeException Unreadable constructor form starting with "#user.x "
clojure.lang.Util.runtimeException (Util.java:170)
[3]
Basically the difference is tagged literals have a space between the tag
and the clojure data.
What are the reasons for this difference? Is there an advantage? To me it
seems too similar that it could be a source of bugs in code.
My pro/con breakdown:
Pro
-Separate "namespace", we can have tags that have the same name as a
classname.
Cons
-Source of compile time bugs when only one is defined. Source of runtime
bugs if both the tag and class exist.
-more work for parsers
