Hmm, depends on how it's implemented. It will most likely not work I
guess.
Nope... eval()'d code is in a separate op_array from the code it's
eval()'d
from. While it has the same variable scope it does not have the same
label
pool. Building in that kind of support is theoretically doable (and
you'd
get support for cross-file gotos in the process), but it complicates
the
execution flow somethin' fierce.
My contention was that eval() should work consistently. Andi
indicated that
there are other language features which would similarly not "work" when
eval()'ed. If that's the case, then not having this work as well, is
fine
with me. (I voted -1 on variable labels even though I voted +1 on
goto.)
Out of curiosity, I wonder which other features would similarly not
work when
eval()'ed...???
break/continue don't work for the same reasons that goto shouldn't.
