Replying to [comment:15 lftabera]:
> Peter, have you considered the impact of using has_coerce_map on the
level of conversion? memory and time consumption.
Not really; my first priority was to get correct behaviour, preferably in
a clean way. The cause of this bug appears to be precisely that the
conversion currently doesn't check if a coercion exists. Do you have an
example in which this patch is too inefficient?
