Dev mode

[Bilge]

The introduction of a developer mode would allow for an opinionated preset to be applied to Porter's features set, in contrast to its defaults, which subsequently enables/disables certain features or modifies default values to be more conducive to development work.

For example, developer mode may:

• reduce automatic retries from 5 -> 1
• <add more ideas here...>

[Bilge]

A better idea might be production mode that removes some unnecessary checks, such as type or method checking, assuming the same code has already been tested prior to production release and is invariant.
