Ever since I read
https://dlang.org/blog/2017/02/13/a-new-import-idiom/ I've
very much enjoyed using the new `from` template. It unlocks
new idioms in D and have been so useful that I thought it
might be a good addition to the core language. I've found
that having it in a different place in each project and always
having to remember to import it makes it much less ubiquitous
for me.
One idea is we could add this template to `object.d`. This
would allow it to be used from any module that uses druntime
without having to import it first. The template itself is
also very friendly to "bloat" because it only has a single
input parameter which is just a string, extremely easy to
memoize. Also, unless it is instantiated, adding it to
object.d will have virtually no overhead (just a few AST nodes
which would dwarfed by what's already in object.d). It would
also be very easy to add, a single PR with 4 lines of code to
druntime and we're done.
Of course, if we don't want to encourage use of the `from`
template then this is not what we'd want. Does anyone have
any data/experience with from? All I know is my own usage so
feel free to chime in with yours.
What uses does this actually have, I only see one example from
the article and it is an oversimplistic example that
effectively translates to either phobos being used or not being
used. All the extra bloat this template would add to the
already bloated if constraints is not welcome at all. The
potential small benefit this might add isn't worth the
unreadable mess it will turn code into.
I can't help but laugh when you say "all the extra bloat this
template would add..." :) Sorry, I don't mean to insult but that
really gave me a laugh.
I hate to be blunt, but its clear from your response that you
failed to grok the original post, which makes anything else I say
pointless. So I'm going to slowly back away from this
one...step...step..step....*stp*....*s*...*
