Yes, perl has a similar method. The following is from the "Programming
Perl" book:

#!/bin/sh -- #perl, to stop looping
eval 'exec /usr/bin/perl -S $0 ${1+"$@"}'
    if 0;

.. rest of perl script ...

It's strange but it seems to work for me. In this case you simply
substitute maybe $GRASS_PERL for /usr/bin/perl.
