There isn't a localization command that I know of but you can use
BLOCK to your advantage for these sorts of issues. INCLUDE makes a
copy of the Stash and so protects you from changes made inside blocks.
(To an extent, anyway). I know that isn't what you are asking for but
it might help.

[% i =3D 3 %]
[% INCLUDE i +%]
i =3D [% i %]

[% BLOCK i %]
inside i=3D[% FOREACH i =3D [ 10..20 ] %][% i %] [% END +%]
[% END %]
