2090. The present subjunctive is particularly common in exemplification.
The perfect is sometimes used in the protasis, rarely in the apodosis:
as,
#sī pater fāna expīlet, indicetne id magistrātibus fīlius?# _Off._ 3,
90, _if a father should plunder temples, would the son report it to the
magistrates?_ #sī quis pater familiās supplicium nōn sūmpserit, utrum is
clēmēns an crūdēlissimus esse videātur?# _C._ 4, 12, _assume for the
sake of argument that a householder have not inflicted punishment, would
he seem merciful, or a monster of cruelty?_ #sī scierīs aspidem occultē
latēre uspiam, et velle aliquem imprūdentem super eam adsīdere, improbē
fēcerīs, nisi monuerīs nē adsīdat#, _Fin._ 2, 59, _suppose a man should
know, e.g. that there was a snake hiding somewhere, and that somebody
was going to sit down on the snake unawares; he would do wrong, if he
did not tell him he must not sit down there_. In such periods the future
is also used, but less frequently: see 2054.
