Developing with strict and then removing it should have no effect at runtime, but you would likely be better served using a persistent execution environment or ByteLoader then by worrying about the relatively small parsing overhead of use strict; and our.

The important feature that strict 'vars' provides is that it enforces declaration of variables, which will catch typos. If you mistype if $DEBUG as if $DEGUB, strict 'vars' will cause an error, while running without strict will cause Perl to silently create a "$DEGUB" variable with an initial undefined value.

Lastly, while our is equivalent to simply running without strict in terms of making global (package) variables available, my actually does alter the semantics of the program. The only bloat you will get from strict is use strict; itself and any use vars or our declarations — all other variable declarations are actually important.
