The q method of quoting strings means that you don't have to escape single quotes in the string.
As per the documentation, it works like this:
q'<single character delimiter><text><single character delimiter>'
Therefore, the !s in your sample string are acting as the quote delimiter.
For example, if you want to use the string Don't worry, be happy, in the old style quoting, that would become:
'Don''t worry, be happy'
but the new quoting mechanism would be:
q'!Don't worry, be happy!'
or
q'{Don't worry, be happy}'
etc.
