3.6. Notes about s2p, the sed-to-perl translator

s2p (sed to perl) is a Perl program to convert sed scripts into the Perl programming language; it is included with many versions of Perl. These problems have been found when using s2p:

(1) Doesn't recognize the semicolon properly after s/// commands.

       s/foo/bar/g;

(2) Doesn't trim trailing whitespace after s/// commands. Even lone trailing spaces, without comments, produce an error.

(3) Doesn't handle multiple commands within braces. E.g.,

       1,4{=;G;}

will produce perl code with missing braces, and miss the second "G" command as well. In fact, any commands after the first one are missed in the perl output script, and the output perl script will also contain mismatched braces.
