- Job:
This pass discards bypasses that are not defined in the current language
If they are really called at runtime, an exception will be thrown

- Precond:
It assumes bypass hoisting has occurred

- Goal:
It is intended for tests, because when the code is not sliced you end up with client bypasses
in your server code or vice versa.

- More precise description of the job:
More precisely, non functional values are treated this way:
[x = \@expanded_bypass(%%max_int%%)
f() = x] becomes
[x(_) = error("max_int was called")
f() = x()]
And functional values are treated this way:
[bypass(x,y) = \@expanded_bypass(%%something%%(x,y))]
becomes
[bypass(_,_) = error("bypass something was called")]

Something went wrong with that request. Please try again.
