Why does the Clojure reader get confused with keywords containing colons? -

from reader docs:

keywords symbols, except:

they can , must begin colon, e.g. :fred.

they cannot contain '.' or name classes.

a keyword begins 2 colons resolved in current namespace

and

a symbol can contain 1 or more non-repeating ':'s.

so looks docs should explicitly allow :my:keyword keyword.

this works in repl:

user=> {:my:keyword 1} {:my:keyword 1} 

and works:

user=> {:mykeyword   #_=> 1} {:mykeyword 1} 

and works

=> (clojure.edn/read-string (pr-str {:my:keyword 1})) {:my:keyword 1} 

but doesn't:

user=> {   #_=> :my:keyword  runtimeexception eof while reading, starting @ line 1 clojure.lang.util.runtimeexception (util.java:221) 

i can't put newline in middle of hashmap literal following keyword containing colon.

i can other keywords. works ok.

user=> {   #_=> :one   #_=> 1   #_=> } {:one 1} 

why? quirk of reader? afaict :my:keyword syntactically valid keyword. should worried other inconsistencies?

i'm using

repl-y 0.3.5, nrepl 0.2.6 clojure 1.6.0 

as last example stands, haven't completed map, expect throw exception value :my:keyword is. works me.

{  :my:keyword 1  } => {:my:keyword 1}
