in thread how to check syntax of code inside a scalar?

This does however seem to match the perl -c syntax check. From perlrun:
       -c   causes Perl to check the syntax of the program and then exit
            without executing it.  Actually, it will execute "BEGIN",
            "UNITCHECK", "CHECK", and "use" blocks, because these are
            considered as occurring outside the execution of your program.
            "INIT" and "END" blocks, however, will be skipped.
perl -c -e 'BEGIN { print "yay\n"; }; print "boo\n"'
yay -e syntax OK
