Am re-opening so that maybe some type-checking can be done in Django to
make for a more helpful error message.

This is a bit too vague to be useful as a suggested improvement. Type-
checking what, exactly?
> You can reproduce this by passing a floating point value (ints don't
trigger this) to a template and using that variable as a view argument
that's expecting a string.
Again, you've left out a lot of details so I have to guess what pattern
you might be using, etc. Guessing you have a pattern like:
{{{
(r'^thing/(?P<pk>\d+)/$', 'thing_detail'),
}}}
If you then try in a template:
{{{
{% url thing_detail magic_number %}
}}}
where magic_number is a float variable in the context, the attempt to
reverse will fail because the string representation of the float will have
a decimal point in it, thus will not patch the `\d+` pattern. Integers
work because their string representation matches the pattern. But it
would be perfectly legitimate to have a url pattern that did match the
string representation of a float, so it isn't like the url tag can
arbitrarily reject float arguments. The best it can do is say there is no
pattern that matches what you've passed it.
If you've got a specific suggestion for improvement feel free to open a
new ticket with recreation details including exactly what you are doing,
what message you get, what you think would be better, and how you think
Django could actually accomplish that. So far as I can tell what you are
asking for here is not something that is possible.
