There are some cases where the '.' character would also match any character and could lead to incorrect results. For example the regular expression - `^ioutils.WriteFile$' would match ioutils.WriteFile, but also ioutils_WriteFile. Additionally made sure that all regexp were declared using raw strings to avoid any unnecesary string escaping that potentially make the regexp difficult to read.
