Perl Kurila is a dialect of Perl. With Perl 5 as ancestor it has a
solid base, but without the backwards compatibility
requirement of Perl 5, it is free to evolve into new directions.

A sugared version of

local $v = $v;

could be

local= $v;

Thanks for your suggestion,
but "local" has already been changed to not reset the the variable.
Thus "local $v" would not set $v to undef, only store the current
value to be restored when exiting the current scope.

This can be used for example with an indentation level:
local $indentation_level += 2;

I suggested an alternative, because there is plenty of code around that
assumes that the localised variable starts out as undef.

For example slurping; in stead of

local $/;

in Kurila that now needs

local $/ = undef;
or
undef local $/;

In Perl 5 you do:

local $indentation_level = $indentation_level + 2;
