write method bug with boolean values

[devsheva]

When you try to use the general write method to write a list of tokens, containing boolean values, it leads to unexpected situations.
For example if a false token is present, it will be wrote as empty string.

I think this happens due to lack of a boolean rule in the write method, unlike the one to identify numbers etc.

Workaround

In case of a false value, force token to string.

token.is_a?(FalseClass) ? "FALSE" : token
