init-list guidance

[vinniefalco]

The rule for construction should be

"Always use () unless you want an array."

Hey @vinniefalco, I am a new contributor. will you please explain this issue? I want to contribute to this repo.

Is this really true? We use init-lists in tests to create objects.

[vinniefalco]

Is this really true?

I'm not sure but I know that init-list construction is problematic because of C++ and there is nothing we can do about it except warn users in the docs.

[grisumbras]

Ah, you mean that we should explicitly dissuade users from using complex init-list expressions?

[vinniefalco]

Something like that, yes. We can probably ignore this until someone reports an actual issue.
