I'd say all extracted lines which pass a syntax check with perl -c without error are per definition perl code.

(I suppose man pages don't include syntactically wrong code).

Anyway you'll run into security issues, because avoiding the execution of BEGIN blocks isn't trivial.

(see Vulnerabilities when editing untrusted code... (Komodo) and especially 847484)

Another option then should be using PPI for a static parse

UPDATE: If you say "analyze a man page" do you mean generated from POD (as IMHO >90% of all mans about Perl should be)? POD has a pretty clear convention to signal embedded code by indentation.

Best solution anyway would be to parse the original POD instead of the man page, some POD parser (like POD::POM )already allow recognizing code sections (but which are not necessarily Perl-code).

If you now run a syntax check on those extracted chunks you should get almost 100% secure results.
