hackage.haskell.org : symbolize
Symbols, also known as Atoms or Interned Strings, are a common technique to reduce memory usage and improve performance when using many small strings. By storing a single copy of each encountered string in a global table and giving out indexes to that table, it is possible to compare strings for equality in constant time, instead of linear (in string size) time. The main advantages of Symbolize over existing symbol table implementations are: Garbage collection: Symbols which are no longer used are automatically cleaned up. Symbols have a memory footprint of exactly 1 Word and are nicely unpacked by GHC. Support for any Textual type, including String, (strict and lazy) Data.Text, (strict and lazy) Data.ByteString etc. Thread-safe. Calls to lookup and unintern are free of atomic memory barriers (and never have to wait on a concurrent thread running intern) Support for a maximum of 2^64 symbols at the same time (you'll probably run out of memory before that point).
