HTML::Template compiles an IF/ELSE into two JUMP IF ops:
JUMP to A IF false
...
...
JUMP TO B IF true
A: ...
...
...
B: ...
Thus a false condition is only tested once, but a true condition gets
tested twice. The trick will be to link the two jumps so that the
second one re-examines the result of the first rather than running the
code again.
