Pipes stdout from the left hand command to stdin of the right hand command
This token behaves much like pipe would in Bash or similar shells. It passes stdout along the pipeline while merging stderr stream with the parents stderr stream.
It can be used interchangeably with the arrow pipe, ->, in shell scripts.
» out Hello, world! | regexp s/world/Earth/
Hello, Earth!
» out Hello, world!|regexp s/world/Earth/
Hello, Earth!
In following example the first command is writing to stderr rather than stdout
so Hello, world! doesn't get pipelined and thus isn't affected by regexp:
» err Hello, world! | regexp s/world/Earth/
Hello, world!
To pipe stderr you'd need to use the <!> syntax. For example <!out> to
write stderr to stdout:
» err <!out> Hello, world! | regexp s/world/Earth/
Hello, Earth!
