It's not impossible, just annoying:
echo 'It'\''s a beautiful day in Canberra'
Speaking of which, Python has the ultra-handing "raw string" quoting
style which is especially good for regular expressions:
print r"Look Mum, \no \\doubled backslashes: here's a newline: \n"
(Yes, I know Perl has even more ways to do this. But this is more
like the smallest necessary syntax.)
