Invalid '==' expression silently ignored leading to invalid result

[anatoly techtonik <techtonik@…>]

Let me clarify the title - I am not sure the expression below is invalid. It is the expression I intuitively expect to work. But perhaps Django it is a specifics of template language. In any case it should either complain or produce expected output, which it doesn't.

_{{ closed }}_
{% if closed == True %} ***** {% endif %}

If closed variable is equal to None, the example above will output the string:

_None_ *****

Expected is to output nothing or to give a warning about invalid right-side argument.

If closed is boolean (not string) and is equal to True, it will output

_True_

Expected is to output

_True_ *****

or to give a warning about invalid right-side argument.
