 It's ugly, violates DRY and feels like you're writing Perl, not Ruby.
 There is a better way.

 Here's how we'd implement the same example with BinData.
 
   class PascalString < BinData::Struct
     uint8  :len,  :value => lambda { data.length }

 This syntax needs explaining.  Let's simplify by examining reading and
 writing separately.
 
   class PascalStringReader < BinData::Struct
     uint8  :len
-    string :data, :initial_length => :len
+    string :data, :read_length => :len
   end
 
 This states that when reading the string, the initial length of the string
 (and hence the number of bytes to read) is determined by the value of the
 +len+ field.
