The objects handled by + and = can be :
- strings, integers, floats
- instances of $TagClass
Still, it tends to be a lot harder to explain, document, and read
documentation for, something that uses operators weirdly, rather than
keyword-searchable method names.

If that's your intention, then instead of coming up with something totally

Because the tree implementation in ElementTree or other tree modules in Python
require a lot of
Pythonic also means:
If the implementation is hard to explain, it's a bad idea.
What, exactly, does the sum of a string and a bolded string produce? Can you
explain that easily and clearly?
Yes : a+b returns the string a+str(b)
It is exactly what you get in CPython with
class B:
...
= is a comparison expression operator, which is completely different.
It is just wrong for this usage. I am 99.9% sure you will come to regret
it eventually. Better to make the change now than in Brython2 or Brython3.
I am 99.99% sure of the contrary, having used this syntax for more than 3
Hmm. So when that gets added into a DIV, it has to get parsed for
tags? How does this work? This seems very odd. I would have expected
it to remain as DOM objects.
In DIV(child) :
- if child is a string, integer or float, a text node is added (addChild) to
the DIV element, with the string
The interpreter, though, will be more than happy to treat that as a
comparison if the LHS is not the type that you think it is. For
example, maybe you've added it to a string at some point, and now it's
a string instead of an element. I guess that since doc is made a
