@ottobackwards Thanks for the +1 and yeah, I definitely hear the concern.
I wanted a rudimentary set of functional primitives, but there should be a
follow-up to correct some issues with them around capability, such as
supporting more complex data structures than lists (i.e. supporting `MAP({
'key' : 'value', 'key2' : 'value2' }, (k,v) -> JOIN([k, v], ':'))` should be
`['key:value', 'key2:value2'])`). In that case, it wouldn't assume a single
argument.
Oh, also, we do actually validate before a zookeeper push all stellar
statements. It will fail if you botch the stellar. I'm looking forward to a
proper UI around stellar, though, for sure. :)
