v0.6.1

• Remove support for quoted expressions as literal patterns. It didn't
  work right, and it interferes with extensions to provide more clever
  introspection in the future.
• Changed from the use of Base.isequal to Rematch2.ismatch for
  compat with Match.jl and to add some flexibility (clients can override
  it for specific types). Then implemented the usual suspects (default to
  isequal) and added support for ranges and regular expressions.
• Added more precise support for macros to support bignums, verbatim
  literals, version identifiers, and other string macros.
• Added support for a Symbol positional pattern (one parameter: its
  string form).
• Removed support for Expr that merely compared with the input using
  isequel. This permits us to add perhaps more flexible expression
  matching in the future.
• Fixed a bug in Match.jl that SubStrings will not match a regular
  expression.
• Add support for pattern, if condition end guard syntax
• Add support for @ismatch macro
• Preserve pattern variable names in the generated code.
• Remove support for let for the @match block.
