I am not quite sure how to reify the graph of lambda terms expressed as parametric HOAS. Is it not possible ?
data PLambda a where
Var ∷ a → PLambda a
Lam ∷ (a → PLambda a) → PLambda a
App ∷ PLambda a → PLambda a → PLambda a
newtype Lambda = Hide { reveal ∷ ∀ a. PLambda a}

I want to check a line for one of 5 matches:

I'm trying to match the text in one block of li tags against another block of li tags, and although this works, there must be a better way of doing it without nested loops.
<ul>
<li>New Ford
<ul class="offersNew">
<li><a href="abc">Ford B-MAX</a></li>
<li><a href="abc">Ford C-MAX<
The following code is not one of my proud moments. In its initial state, I had only a single purpose, but know I'm up to three purposes and I don't know if it would stop there.

Tile t = (Tile) 5;
string s = TileToString(t);
An enum is a set of names for numbers, effectively... but neither the compiler nor the CLR enforces that a value of the enum type has a name. It's a pain, but there it is...

The method medianOfThree
returns the median of the first, center and last element in array
sorts the first, center, and last element of the array, so they are in order EXCEPT places the center in the second to last position.
Examples:
INPUT: 1,2,3
RETURN:2
EFFECT:1,2,3
INPUT: 3,2,1
