maximum of random variables

[CognitiveGrowth]

I expected max(normal(0,1),normal(0,1)) to generate a random variable that is the maximum of two standard normal random variables. Instead, it causes the following error:

Error: Wrong inputs / Logically impossible
Stack trace:
at line 6, column 1

Is this a bug, or am I do something wrong? How else would you generate the maximum of two random variables in Squiggle?

It's a bug, but there's a workaround.

The problem is that max only works on sampleset distributions, so you have to convert both arguments to samplesets:
max(normal(0,1)->SampleSet.fromDist,normal(0,1)->SampleSet.fromDist)

I filed an issue for this: #1409

Thank you very much! This workaround allowed me to achieve what I needed to do. :)

I think @berekuk's answer is good here. I'm really not sure if we should support a "max" on most symbolic/pointset dists, as it's often technically infinity.
