declares that the current script is the user profile
then evaluates and auto-prints the sub-expressions of its argument.

## if you wish to use this.path() in a user profile,
## instead of writing:

## <expr 2>
## <...>
##
## write this:
##
## this.path::with_init.file({
## <expr 1>
## <expr 2>
## <...>
