<h3>Lambda/Function Syntax</h3>
|
|
|
|
|
named function (added to scope, not applied): <code>(swap; a b -> b a)</code>
|
|
|
|
|
<br>
|
|
|
|
|
can be called later like: <code>1 2 swap</code>
|
|
|
|
|
<br>
|
|
|
|
|
unnamed function, applied immediately: <code>1 2 3 (a b c -> a b c)</code>
|
|
|
|
|
<br>
|
|
|
|
|
when lambdas return, they return entire stacks, which are sequentially applied back onto the stack
|
|
|
|
|
<h3>Partial Application</h3>
|
|
|
|
|
<code>1 +</code> will push a partially-applied function onto the stack
|
|
|
|
|
<br>
|
|
|
|
|
this could be called with: <code>1 + (partial -> 2 partial)</code>
|
|
|
|
|
<h3>Pairs</h3>
|
|
|
|
|
pairs of 2 values can be created with <code>pair</code>
|
|
|
|
|
<br>
|
|
|
|
|
they can be deconstructed using <code>fst</code> or <code>snd</code>
