Code​:
my $x; $x = 50; 42 = $x

Result​:
Cannot modify an immutable Int
  in block <unit> at -e line 1

So which one of the assignments actually failed (both are on the same line)?

This bug report is motivated by this thinkperl6 exercise​:

� We�ve seen that $n = 42 is legal. What about 42 = $n?

I think a good error message would be �Cannot modify an immutable Int (42)�, or whatever else which includes the value itself.
