I wondered if there was a neat way of foreaching through a list of varibles that are names sequentially

There is, but don't do it. That may sound harsh, but use of symbolic variables is almost categorically a bad thing as a certain Mr. Dominus illustrates in Why it's stupid to `use a variable as a variable name' (with follow up articles here and here).

The alternatives are either creating an array instead of dynamically generating variables, or just use a hash e.g

## using an array

my @calcs = some_function();
for(@calcs[0 .. 3]) { ... }

## using a hash

for my $k (map "calc$_", 1 .. 4) {
  do_stuff( $calc{$k} );
  ...
}
