You get a tick for each line ; and each block {}
Try that:
declare(ticks=1) echo 'foo!bar';
No block, no extra tick.
declare(ticks=1) {{ echo 'foo!bar'; }}
More extraneous blocks = more ticks.
PS: by the way, ticks are quite the exotic feature and they're only useful in a few extremely rare situations. They are not equivalent to threading or anything. If, for you, ticks are the solution to a problem then you should post about your problem in another question because it's probably not the right solution to it.
