New experimental feature - syntax highlighting using xonsh prompt:
If you're using xonsh prompt and want to use pipeliner with syntax highlighting instead of string there is experimental
feature that catch `pl (<python>)` calls and uses the expression from the xonsh python substitution as pipeliner argument.
Example:
bash
echo echo | pl (line + '!')
In the xonsh prompt it's equals to:
echo echo | pl "line + '!'"
