The problem with this formulation is that a successful 'when'
exits the block, while a successful 'if' does not. This is one
of the significant differences between 'if' and 'when'.
So in the above, the default say "tock" is executed regardless
of the result of the time > $limit test.

It's not as easy to do both as your example seems to illustrate.
Perhaps you can provide a better example that does illustrate
testing for a condition that also results in exiting the C<given>
block?
