{{{
@register.simple_tag(takes_context=True)
def my_tag(context, arg1, *, kwarg2='n/a'):

}}}
Html code
{{{
<div>bla bla bla</div>
{% my_tag 'arg_1_value' kwarg_2='kwarg_value' %}

Result
{{{
ValueError: Function has keyword-only arguments or annotations, use getfullargspec() API which can support them
}}}
