trypipe)Checks for non-zero exits of each function in a pipeline
trypipe checks the state of each function and exits the
block if any of them fail. Where trypipe differs from
regular try blocks is trypipe will check every
process along the pipeline as well as the terminating function (which
try only validates against). The downside to this is that
piped functions can no longer run in parallel.
trypipe { code-block } -> <stdout>
<stdin> -> trypipe { -> code-block } -> <stdout>trypipe {
out "Hello, World!" -> grep: "non-existent string" -> cat
out "This command will be ignored"

the formatter (pretty) fails (eg input isn’t valid
JSON):
func pless {

}A failure is determined by:
You can see which run mode your functions are executing under via the
fid-list command.
