[perl #124079] no exception for type mismatch while assigning to typed array when assignment is followed by unrelated code

[Christian Bartolomaeus via RT]

On glr the evaluation dies with X::TypeCheck::Assignment:

$ perl6-m -e 'my Str @a = (1, 2); 1'
WARNINGS:
Useless use of constant integer 1 in sink context (line 1)
Type check failed in assignment to '@a'; expected 'Str' but got 'Int'
  in block <unit> at -e:1

The test in S09-typed-arrays/arrays.t was unfudged with commit 
https://github.com/perl6/roast/commit/f5c11d03d2.

I'm closing this ticket as 'resolved'.
