I do not necessarily have a strong preference between "to" and "from". I am not a
native english speaker either; maybe it is best if a native english speaker could
share an opinion in regards to (perceived) differences, when comparing "to" and
"from" here.
As for the backtrace situation: I think different ruby users and devs may have
a different preference. I do not have a strong preference; I can adjust fine to
the changed backstrace. I may perhaps slightly prefer the older one but I have
no strong preference here really - whatever the ruby team wishes to use as the
default. I do, however had, think that ultimately it would be best if these
aspects could be controlled in some way - I think I used comparisons to that
with warnings in the past, and Warning has been extended over the last months
(or years). Perhaps in the long run, when it becomes more clear, we can look
which use cases may be the most common for people to use, and support these
(e. g. make the "best" as the default, but allow people to customize what
they want to use, ideally, including things such as warnings, but also the
display of the backtrace and so on; I think there was once a japanese ruby
user who wrote that he was confused by the changed backtrace, so simple means
to regulate that may be helpful, e. g. like the idea behind rubocop allowing
customization for a project/team). But back to your original suggestion, I
do not have a strong preference either way. Actually if it were up to me I
may even use a much longer, more descriptive error reporting, if it can be
made more useful. Something like some "report" tool or so that could tell
things such as:
"On line 33 you possibly forgot an 'end'."
Or something like that ... it is actually quite difficult to provide good
error messages that are easily understandable, without letting the user
guess. :)
And I think the ruby core team and matz prefer shorter/more succinct variants,
so this should, if anything, more be an option - but anyway, I digress.
Don't want to distract from sawa's suggestion and should rather make a
separate one in that case; consider this more like some loose thoughts
about the topic. I remember that it can be really difficult to know
what is going on if the backtrack strace is very long; like having to
scroll up hundreds to thousand of lines, only to see the error on top
was due to a single letter typo. That is also a reason why perhaps
bottom-error reporting may seem more convenient, for quick results.
But again, sorry - I digress.
