Different behaviour of reader for invalid token expression

[Juan Facorro]

Describe the bug
Entering the following expression in the REPL provides different results:

:{:a 1}

To Reproduce

In a clojerl REPL enter the following :{:a 1}.

Expected behavior

Should behave in the same way as in Clojure JVM:

Clojure 1.10.0
user=> :{:a 1}
Syntax error reading source at (REPL:1:2).
Invalid token: :
{:a 1}
user=>

Actual behavior

Clojure 0.7.1-2136.4a5b16c
clje.user=> :{:a 1}
#error {
 :type clojerl.Error
 :message NO_SOURCE_FILE:1:2: Invalid token: :}
:a
1
clje.user=>

Context

• clojerl version (tag/sha): 0.7.1-132-g4a5b16c

[Juan Facorro]

There are other input strings in the REPL that will not be read correctly:

1{}

:{}

#?(1{}

\1234{}

foo:{}

Basically any input that will generate an error and doesn't include whitespace between the last character that generates the error and the next expression.
