muSE - short for 'muvee Symbolic Expressions' - is a Scheme dialect intended for use as an embedded language. It has some unique language features such as first class macros, simple general read-time evaluation syntax, vectors and hashtables that can be used as functions, and extensive use of pattern matching bind.

Highlight: muSE is used as an embedded language to specify the "styles" in muvee Reveal, launched on 11 June 2008.

• Provides lexically scoped closures as well as dynamically scoped blocks.
• Expressive reader macro system where macros are first class citizens (i.e. can be passed around as arguments to functions, assigned to variables, etc.)
• Uniform use of pattern matching for variable binding.
• Generic functions (doc)
• Many polymorphic primitives - including map, filter, reduce, get, put, and some others.
• An extremely easy to use Objective-C bridge (only on MacOSX).
• A simple module system.
• Flexible exception handling
  • Resumable exceptions
  • Exception handler dispatch using pattern matching bind.
  • Simple cleanup mechanism
• Reduce the need for local variables using TheAndIt.
• Built-in support for JSON.
• Built-in support for reading/writing a subset of XML.

• C-based, fairly well documented, simple embedding API. Can call as well as be called from C/C++ code.
• Compact - Its easy to strip down the feature set to whatever subset of the core language you need.
• Extensible notion of objects to add new kinds of things to muSE in native code. Vectors, hashtables and ports (for I/O) are provided using this mechanism.
• Ability to add C/C++ based native functionality in the form of plugin DLLs.
• Ability to create StandAloneExecutables
• Supports multiple independent environments
• Liberal license terms - can use in commercial applications without publishing source code.

The license agreement has been changed (13Nov2008) to "New BSD" with the requirement that contributions be made on the same terms.
