F# Equivalent of Python range
<p>I've started learning F#, and one thing I've run into is I don't know any way to express the equivalent of the <code>range</code> function in Python. I know <code>[1..12]</code> is the equivalent of range(1,13). But what I want to be able to do is <code>range(3, 20, 2)</code> (I know Haskell has <code>[3,5..19]</code>). How can I express this?</p>
