Question : How to check if value in a list in Perl?

Hi,

I am trying to create a conditional statement "if" that will check if a value is in a list of values. Right now, I simply do this:

if ( $myvar == 'VAR0123' || $myvar == 'VAR1234' || $myvar == 'VAR2345' )
{
}

I would prefer to setup all my "values" in an array or hash at one place and then do something like:

if ( $myvar ISIN $mylist )
{
}

Can this be done easily in Perl? Maybe using a hash table? Any ideas?

generally, $mylist{$myvar} would be better for this kind of thing than grep or foreach or =~
$i == 'VAR0123'
will match anything that does not look like a number
