The do-BLOCK construct does not allow statement modifiers.

:    { say } for 1..3;
: 
:    -> $i { say $i } for 1..3;

These are both legal syntactically, but neither of these do anything
other than produce a closure muliple times without calling it.

: as  while, given, if, until, and unless?

Same.  Will clarify S04.
