yep but as you said it's only runtime.

But it should be feasible to write a an op-code walker catching them at compile time in the UNITCHECK phase.

D:\>perl -MO=Terse -E "use strict; say @@"
LISTOP (0x2820630) leave [1]
    OP (0x2820600) enter
    COP (0x2820670) nextstate
    LISTOP (0x2820700) say
        OP (0x28206d0) pushmark
        UNOP (0x2820740) rv2av [2]                      <-- array
            PADOP (0x2820778) gv  GV (0x1dede0) *@      <-- of glob *@
-e syntax OK

D:\>perl -MO=Concise -E "use strict; say @@"
7  <@> leave[1 ref] vKP/REFC ->(end)
1     <0> enter ->2
2     <;> nextstate(main 48 -e:1) v:%,*,&,{,x*,x&,x$,$,469764096 ->3
6     <@> say vK ->7
3        <0> pushmark s ->4
5        <1> rv2av[t2] lK/3 ->6                         <-- array
4           <#> gv[*@] s ->5                            <-- of glob *@
-e syntax OK
