Things to do:

• Add all the missing mapping logic (should satisfy the acceptance tests)
• Synchronize preparation (compilation) process
• Add a way to control whether code gen is used
• Run relevant tests for both modes (ExecutionMode.Auto and .Reflection)
• Attempt compilation once and if it fails fall back to reflection, log a message for the user to create a ticket. On the next calls, do not attempt to compile again. Disable this functionality in acceptance tests.
• Consider deactivation of high performance optimizations (mainly for argument parsing)
• Consider unit tests for code generation path
• Benchmark differences
• Consider reworking MethodCollection to be generated as well (at least optimize the class)
• Consider changing the API to allow initialization at boot instead of first request
• Consider adding identifiers to argument parsers and injectors to allow them to being directly used in the generated code instead of looping through them
• Consider reworking routing from regex into segment-based, advance-capable routing (do we need a Rewind() btw. to be correct?). Could be a type with either a string or a regex segment. Also consider using stackalloc based lists to avoid the allocations there.
