Expected Behavior

I expected a clean compile, as with previous versions.

Current Behavior

Can you try again using a fresh V version?

[BMJHayward]

`v -version

V 0.3.2 46f1b20`

v -keepc -cg -showcc .
/home/brendan/code/v/vlib/rand/rand.v:345:30: error: unexpected token `[`, expecting `(`
  343 | // shuffle all elements until the end.
  344 | [direct_array_access]
  345 | pub fn (mut rng PRNG) shuffle[T](mut a []T, config config.ShuffleConfigStruct) ! {
      |                              ^
  346 |     config.validate_for(a)!
  347 |     new_end := if config.end == 0 { a.len } else { config.end }

and v up gives:

cannot compile `/home/brendan/code/v/cmd/tools/vup.v`: 
/home/brendan/code/v/vlib/os/file.c.v:591:32: error: unexpected token `[`, expecting `(`

Still a bit stuck

[JalonSolov]

Is this still an issue with current V?
