Something like the attached?

$ ./perl -e 'push %x,1;' -e 'pop %x;' -e 'push *x,1;' -e 'pop *x;'
Type of arg 1 to push must be array (not hash dereference) at -e line 1, near "1;"
Type of arg 1 to pop must be array (not hash dereference) at -e line 2, near "%x;"
Type of arg 1 to push must be array (not ref-to-glob cast) at -e line 3, near "1;"
Type of arg 1 to pop must be array (not ref-to-glob cast) at -e line 4, near "*x;"
Execution of -e aborted due to compilation errors.

which matches what older perls did for the same code:

 *x;'
Type of arg 1 to push must be array (not hash dereference) at -e line 1, near "1;"
Type of arg 1 to pop must be array (not hash dereference) at -e line 2, near "%x;"
Type of arg 1 to push must be array (not ref-to-glob cast) at -e line 3, near "1;"
Type of arg 1 to pop must be array (not ref-to-glob cast) at -e line 4, near "*x;"
Execution of -e aborted due to compilation errors.

without removing the useful message that the experimental feature has been removed.
