Imperative used instead of conditional form


This quesion:

[と言っても vs とは言え
.](https://japanese.stackexchange.com/questions/2030/%e3%81%a8%e8%a8%80%e3%81%a3%e3%81%a6%e3%82%82-vs-%e3%81%a8%e3%81%af%e8%a8%80%e3%81%88)

reminded me of a similar case:

> どっちにしても vs どっちにしろ

which are also synonymous as far as I can tell.

That got me thinking:

Is this coincidental? Are there other cases where the imperative is used
instead of the conditional formulation? Has this replacement ever been
productive?




This is a remnant of the Classical Japanese form named
「[命令形]{めいれいけい}の[放任法]{ほうにんほう}」. 命令形 means "imperative form",
放任、”noninterference”, "permission", etc. and 法, "rule".

Native speakers, young or old, still use the 命令形の放任法 on a daily basis, but
very few Japanese-learners seem to be able use it actively.

In short, the nuance of this form is "Do as you like." 「どっちにしろ（or せよ）」 means
"whichever you take/choose" and the speaker could not care less which one
someone selects.
