File with just `+` does not report syntax error

[lucacasonato]

Create a file main.ts.

+

Then run deno info main.ts

No diagnostic is raised.

Change the file to:

a+

Running deno info main.ts now:

error: The module's source code could not be parsed: Expression expected at file:///home/lucacasonato/Downloads/publishing_tasks_903afdc4-681b-403c-bc23-1768af7eaad9/index.ts:1:2

  a+
   ~

Same issue with:

void

This is by design. Certain diagnostics are only surfaced when transpiling:

> deno run main.ts 
error: Expression expected at file:///V:/scratch/main.ts:1:1

  +
  ~

The main reason for this issue was resolved in https://github.com/denoland/deno/pull/24620

Maybe we should close this one?
