You could automatically convert from a custom format like that in your 
original post:

import re

_lookup = {
    "[[": "{",
    "]]": "}",
    "{": "{{",
    "}": "}}",
}

def _substitute(m):
    return _lookup[m.group()]

def custom_format(template, *args, **kw):
    return (re.compile(r"\[\[|]]|\{|\}")
            .sub(_substitute, template)
            .format(*args, **kw))

code = "class [[0]]Model { public bool IsModel(){ return a[42] || true; } }"
print custom_format(code, "My")
