Define STRFTIME/MOMENT/MOMENT-MS/RSS-DATE

(Also define str and leftpad)

I wanted to get another set of eyes on this before merging. strftime isn't meant to be a complete implementation, but it's pretty close.

My eyes are not very useful when there aren't tests to run. But these are new functions so no worries. I assume you're running them in laarc? Please remember to backport bugfixes as you run into them.

Oh also, it may be convenient to add some examples just from things you try out at the repl. Easier than installing hg and unit-test.arc.

Do we need this, when we have string?

[shawwn]

Possibly. (coerce x 'string) behaves differently from (+ "" x).

[akkartik]

In what situation?

[shawwn]

In no situations. Never mind, I was mistaken. :)

One benefit of adding a str function is that it can be a place to do things like printing a hash table using curly brace syntax. But that's work for some other time. I'll get rid of str.

[akkartik]

Also, feel free to overload string for those purposes.

(I don't particularly what the function is called. But it seems good to have one strong default.)

I assume you're running them in laarc?

Yup! Previously I was shelling out to date using system, but that's very slow.

Please remember to backport bugfixes as you run into them.

No need to port bug fixes when the code is flawless. /s

(Good point! I'll be sure to port any fixes that come up.)

Good idea!
