(read)
(read reader)
(read opts reader)
(read reader eof-error? eof-value)
Reads the first object from an IPushbackReader or a java.io.PushbackReader.
Returns the object read. If EOF, throws if eof-error? is true.
Otherwise returns sentinel. If no stream is providen, *in* will be used.
Opts is a persistent map with valid keys:
:read-cond - :allow to process reader conditionals, or
:preserve to keep all branches
:features - persistent set of feature keywords for reader conditionals
:eof - on eof, return value unless :eofthrow, then throw.
if not specified, will throw
***WARNING***
Note that read can execute code (controlled by *read-eval*),
and as such should be used only with trusted sources.
To read data structures only, use clojure.tools.reader.edn/read
Note that the function signature of clojure.tools.reader/read and
clojure.tools.reader.edn/read is not the same for eof-handling
