in bash to read bash-formatted variable assignments into the current environment. In other words, the dot ("source") command supports reading from process substitution.
some_command | . /dev/stdin
on the other hand does not work, I guess because it's running in a subshell…?
Replace some_command with something like echo foo=bar if you don't quite understand what I mean.
yep, each command in a pipeline is executed in a subshell, according to the bash man page the last one might not (and rather run in the current shell context) if the lastpipe shell option is set
