You can't include a module into your program just by putting its name in the arguments list. They must be included at compile time by using the use statement or at execution time by using require and import.
Maybe one way to do what you want could be:

my $Measure = shift;
eval "require $Measure;import $Measure;";

## Now, luckily you can use it:
$Measure->new();
