A correct analysis follows. The candidates are:
0: C(params string[]) in its normal form
1: C(params string[]) in its expanded form

Simply turn the array into a hash:
my %params = map { $_ => 1 } @badparams;
if(exists($params{$someparam})) { ... }
You can also add more (unique) params to the list:
$params{$newparam} = 1;
And later get a list of (unique) params back:
@badparams = keys...

Or,
