 Regular expressions can be concatenated to form new regular
 expressions; if \emph{A} and \emph{B} are both regular expressions,
! then \emph{AB} is also a regular expression. If a string \emph{p}
! matches A and another string \emph{q} matches B, the string \emph{pq}
! will match AB if \emph{A} and \emph{B} do no specify boundary
! conditions that are no longer satisfied by \emph{pq}. Thus, complex
 expressions can easily be constructed from simpler primitive
 expressions like the ones described here. For details of the theory

 Regular expressions can be concatenated to form new regular
 expressions; if \emph{A} and \emph{B} are both regular expressions,
! then \emph{AB} is also a regular expression. In general, if a string
! \emph{p} matches \emph{A} and another string \emph{q} matches \emph{B},
! the string \emph{pq} will match AB. This holds unless \emph{A} or
! \emph{B} contain low precedence operations; boundary conditions between
! \emph{A} and \emph{B}; or have numbered group references. Thus, complex
 expressions can easily be constructed from simpler primitive
 expressions like the ones described here. For details of the theory
