export fn name(...) is a C function by that name (numbers, bool, char, pointers in and out). --shared builds lib<name>.so / <name>.dll with no main. finch_module_on_fatal(handler) lets the host take runtime errors over (longjmp out) instead of the process exiting. tests/shared.sh: a C host loads one, calls it and survives an index error.
