forced to use Lua5.1 (2012)

[Moses Moore]

Severity: minor, feature request

Steps to reproduce:
 - apt install lua-check
 - luacheck -v

Seen:
 - lua-check depends on lua5.1, which forces system-wide change of `lua` to `lua5.1`
 - even after using `update-alternatives` to revert system back to using lua5.3, luacheck -v reports "Luacheck: 0.21.1 \ Lua: Lua 5.1"
 - Luacheck version 0.21.1 was 2017-09-10, two and a half years after Lua5.3 became the current version.

Expected:
 - lua-check depends on lua-any (is it possible? is it feasible?)

Other info:
  - luacheck must force the lua version to use, because lua(5.1|5.2|5.3) searches only versioned paths for libraries -- if the luacheck libraries are in the "5.1" paths, then the "5.3" interpreter won't see them.

Workaround: after installing package lua-check
  - update-alternatives --install /usr/bin/lua lua-interpreter /usr/bin/lua5.3 130 --slave /usr/share/man/man1/lua.1.gz lua-manual /usr/share/man/man1/lua5.3.1.gz
  - update-alternatives --install /usr/bin/luac lua-compiler /usr/bin/luac5.3 130 --slave /usr/share/man/man1/luac.1.gz lua-compiler-manual /usr/share/man/man1/luac5.3.1.gz
  - mkdir -p /usr/local/share/lua/5.3
  - ln -s /usr/share/lua/5.1/luacheck /usr/local/share/lua/5.3/luacheck
  - perl -pi -e 's/env lua5.1/env lua5.3/' /usr/bin/luacheck

I acknowledge that this is not a "bug" per se; I don't know how else to make a change request.
