I'm not convinced your endeavour is worthwhile, but I did find a problem.

Assuming it works at all, unslice executes too late in 

unslice 'SomeModule';
use SomeModule;

[download]

It needs to be 

BEGIN { unslice 'SomeModule'; }
use SomeModule;

[download]

A better syntax might be 

no slice 'SomeModule';
use SomeModule;

[download]

Further more, your slice isn't constant. You might as well remove the prototype. Using the () prototype is not enough to make a constant. The body of the function must also be constant. From perlsub:

Functions with a prototype of () are potential candidates for inlining. If the result after optimization and constant folding is either a constant or a lexically-scoped scalar which has no other references, then it will be used in place of function calls made without &.
