In my playing around with it just now, the addition doesn't seem to
actually return a string. I typed this script into the test console:
log('hello ' + B('world'))
and clicked Run, and the result was:
[object Object]
whereas if I just try to log a plain string literal, it actually
prints out the string. Somewhat disturbingly, this also gives the
[object Object] result:
log(str('hello ' + B('world')))
In Brython, the str builtin does not return strings?
