Practically not a fan of it because it has to examine the command,
calculate and make sure it doesn't make changes in the calling shell
that $() shouldn't.  This involves commands that may be functions.  I
also don't like changing `$()`'s behavior through a flag as it will
now be a factor to consider when reading code.

I suggested a solution instead with another syntax.  See
