various globals cleanups
Browse files Browse the repository at this point in the history
- simplify float.jl loop not to call functions just defined to get back
  the value just stored there
- add method to the correct checkbounds function (instead of a local)
- missing world push/pop around jl_interpret_toplevel_thunk after #56509
- jl_lineno use maybe missed in #53799
- add some debugging dump for scm_to_julia_ mistakes
