> For user command `perl -Mbignum=bpi -wle 'print bpi(2000)'` what will be
actually executed in the pod? It seems that it will be `perl -Mbignum=bpi -wle
print bpi(2000)` in this PR? I'm not sure if I understand correctly
The actual command is `perl -Mbignum=bpi -wle "print bpi(2000)"`, if we
don't remove quotes, the command will be `perl -Mbignum=bpi -wle '"print
bpi(2000)"'` and cause error: `Useless use of a constant ("print bpi(2000)") in
void context at -e line 1.`
