Exceptions in langur are hashes that are guaranteed to always contain certain fields.
There is no explicit try block.

val .U1 = h{"msg": "U1"}
val .baz = f(.i) throw if .i > 0 {.U1} else {.U0} ~ h{"src": ".baz"}
val .bar = f(.i) .baz(.i)
val .foo = f(.i) {
.bar(.i)
catch if .err["msg"] == .U0["msg"] {
writeln "caught .U0 in .foo()"
} else {
