Still trying to figure out a reasonable debugging strategy. I keep going back and forth between Debugger and VSCode and can’t get either to work adequately. Biggest problem with VSCode is I can’t understand error messages, especially, for example, when an appropriate method can not be found. It’s also real slow every time a new debug session is started. This problem thought is going back to Debugger after VSCode frustration. Example:

```julia
> julia
               _
   _ _ _(_)_ | Documentation: https://docs.julialang.org
  (_) | (_) (_) |
   _ _ _| |_ __ _ | Type "?" for help, "]?" for Pkg help.
  | | | | | | |/ _` | |
  | | |_| | | | (_| | | Version 1.6.3 (2021-09-23)
 _/ |\ __'_|_|_|\__'_| | Official https://julialang.org/ release
|__/ |

julia> using Debugger

julia> function tst(f0::Float64)
         k1 = 2.0*f0;
       end
tst (generic function with 1 method)

julia> @enter tst(1.0/16.0)
In tst(f0) at REPL[2]:1
 1 function tst(f0::Float64)
>2 k1 = 2.0*f0;
 3 end

About to run: (*)(2.0, 0.0625)

```

Any ideas on what I am doing wrong?

I tried your example in 1.6.2, 1.6.3 and 1.6.4 but all worked well, no error for me.  
Perhaps it’s some older Debugger version you have:

```julia
(@v1.6) pkg> st Debugger
      Status `C:\Users\user\.julia\environments\v1.6\Project.toml`
  [31a5f54b] Debugger v0.6.8

```

And, perhaps also a difference: I am on Windows.
