Elm 0.12.1: Fast immutable arrays

I think this means to say fast persistent arrays. A fast immutable array is trivial - just use an array!

When I read elm I thought it was about an email client. I think that makes me officially very old.<p>I miss those email clients. They were much nicer than most of the email software which is considered modern today.

Couldn&#x27;t they just use Mori?

Logarithmic is not constant.<p>The fact that elm announces constant array access will not surprise anybody, as this is an inherent property of arrays. But then seeing that they have to use radix-trees for arrays and announcing it as constant is highly misleading. These guys should switch over to politics.<p>And this only holds for immutable arrays! So even without push,pop,shift,unshift they have to use trees for arrays.
