2022-07-15: Fuzion July Update

Hi,

Here is this month's update:

The main improvements in June affect the internals: adding static analysis and reducing the size of the bugs backlog.

• fz command
  • added escape analysis required for tail recursion optimization
  • added tail call detection required for tail recursion optimization
• C backend
  • added tail recursion optimization
    • this was long overdue since there are no loops in the intermediate representation resulting in stack overflows for loops with large iteration counts.
• Language Server
  • updated: vscode extension, language server, playground v0.75
  • support semantic tokens, which allows prettier syntax highlighting like this:
    
  • improved expression completion; suggest types where applicable (this is still WIP)
  • inlay hints: show the inferred type of a feature
• Bugs
  • fixed: #327, #326, #325, #320, #317, #296, #293, #292, #277, #264, #261, #256, #236, #133, #45

Cheers,

--Fridtjof.
