Set Extraction KeepSingleton: an option for not decapsulating singleton types
A informative inductive type with one constructor C and one informative arg to C
is normally extracted as an identity, with C removed, see for example
the "sig" type. When this new option is set, these singleton types
are left untouch, providing extracted code which is closer to the initial
Coq development.
Feature requested by Wouter Swiestra.
