How to build the design?

There are design
$var = $meta -> val3;
If you write
$var = $meta -> $a;

It all works.
And how to do without the intermediate variable $a?
i.e. how to build the expression of the val3 (using the value of the variable $i=3) directly into design $meta -> ??

$meta->{'val' . '3'}
