Very unfriendly compiler error

[phated]

If a user writes this program:

let foo = ""

foo.charAt(0)

Nothing is reported in the LSP, and then when you go to compile the program, the compiler crashes with:

grainc.exe: internal error, uncaught exception:
                   (Failure "Impossible: deprecated error type in typetexp")

I was only able to debug this by changing the compiler to output the identifier name. How should we handle this better?

I'll take a look at why the LSP is silent

[marcusroberts]

Oh, it will be if the compiler errors. It should indicate there's been a problem though I think,

@marcusroberts it's silent because it's an error that's not handled by the compiler.
