Currently CPS simply left the procedures untouched during docgen. This causes problems when code for
whelpgets sem-ed, breaking docgen.This commit implements a couple docgen shims:
cpsnow result in a{.cps: baseType.}pragma tagged to the resulting procedure and will show up in the generated documentation.whelpwill generatenilcontinuation for the base type of a cps proc. Parameters that are supposed to go on the bootstrap are added usinglet {.used.}, which should allow their effects to be reflected in the generated docs.whelpwill generate aCallbackwith a factory type that yields a the base continuation type, not the environment type. This should work for most cases when docgen are concerned.This worked well enough for
insideoutdocs to be generated successfully under NimSkull.
