Strict is a compile-time thing. You only pay once each time you turn it on or off, and it sets flag bits on the op nodes in the optree. There's no runtime penalty as such.

OTOH, I think you probably ought not do it. Use real sub refs, and if you need symbolic lookups, look them up in a hash that you've previously populated. There's more and better error checking that way.
