in reply to Template::Toolkit: better way to generate variable names?

Did you try this? 
[%
    foo_1 = 'value1'
    foo_2 = 'value2'
    foo_3 = 'value3'
    foo_4 = 'value4'
    foo_5 = 'value5'
%]
[% FOREACH n = [ 1 .. 5 ] %]
    [% 'foo_' _ n %] is [% ${ "foo_$n" } %]
[% END %]

Anyway, apply here the usual arguments against variable variable names. Use a hash or an array, if you can.

Update: I misread the question. See geektron's reply.

    i really don't need a hash or array in this case.

    if it were straight perl, i would have done: 

    foreach my $counterVar ( 1 .. 5 ) {
   $foo = "string" . $counterVar;
}

    the issue was with the TT meta-language, really. it *can* get a bit odd...

    what i *do* need out of the suggestion is: 

       [% SET FOO = 'string' _$n %]

    [download]
    -- i do need to double-check the underscore location ... --

    after reading the previous reply, the connection between TT's meta-language and 'core perl' kicked in.
