Hello!

In VS Code suppose I have the following snippet:

```julia
if isa(true,Bool)
    println("This is true")
end

if true isa Bool
    println("This is true too")
end

```

You even see how the code statement here actually renders it correctly, but in VS Code:

You see how “isa” is not coloured yellow in the second approach.

Kind regards

I think this is quite consistent. _Function calls_ are coloured yellow, but infix notation is not colored yellow (`a in b` vs `in(a,b)` does the same for example).

If you use my [Julia Color Themes](https://marketplace.visualstudio.com/items?itemName=cameronbieganek.julia-color-themes), then the second `isa` is colored the same as other infix operators:

There are various other Julia optimizations, like the `end` being colored a darker shade of red then the `if` and `for` keywords.

I wonder If someone made a custom theme where the `end` keyword is transparent, making julia code look like python 🤔

I think that would not be a good idea. If you miss to type end, you would get errors, but not see that that is the cause of error.
