"const" can produce broken code

[jofo-ivbar]

I can't get the "const" keyword to work properly for string values:

In [12]: fastjsonschema.compile({"const": "a"})("a")
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-12-ab19503ee02c> in <module>()
----> 1 fastjsonschema.compile({"const": "a"})("a")

<string> in validate(data)

NameError: name 'a' is not defined

Looking the code produced by the compile_to_code function, it seems that the value "a" is just not properly quoted:

VERSION = "2.3"
from fastjsonschema import JsonSchemaException


NoneType = type(None)

def validate(data):
    if data != a:
        raise JsonSchemaException("data must be same as const definition")
    return data

Indeed, it works for values that don't require quoting, like integers.

Good catch! Fixed in master and I will publish in v2.4 it sometime today.
