I have a problem programming uniform networks, "x nodes with y links" that turn 
out to be really hairy to solve for me and i feel i really lack the programming 
features 

"Actually i program in javascript" but the problem seem general for all 
programming languages including Pyhton.

For a beautiful solution it would require "If in list/array return boolean" "If 
not in list/array return boolean". 

But there is no such feature Python nor Javascript, so instead i set boolean 
value "inlist" to false and loop thru, to see if it is already in list. If not 
it is added to list. 

So if the current node i generate links for is x and i try to generate a link 
to  node z, and z's links exhausted i will add it to exhausted list.

And if there is node-x exhausted entries in list, well then script should break 
because it will lock into a cycle. The cyclic lockup is due to only a subset of 
the networks on the form (links*deep)+1=nodes is possible.

So what i need is to know howto write "if list/array ***empty*** do {something}"

I sure know howto check if an array have 1 element 2,3,4 but how do you check 
for empty.

I think it is crazy that you can not do general comparissons of the type 
If in list/array
If not in list/array

But it is even more crazy that you can not check if list/array is empty, that 
is just madness.
