Code:
say ‘hello’.
say 42

Result:
===SORRY!=== Error while compiling -e
Two terms in a row
at -e:2
------> say⏏ 42
    expecting any of:
        infix
        infix stopper
        postfix
        statement end
        statement modifier
        statement modifier loop


This bug report was motivated by this task from thinkperl6 book:

• What if you put a period at the end of a statement?


Arguably, it can probably figure out that . was used instead of ;. The problem 
is that . is interpreted as an infix, and therefore it only blows up when it 
sees the next occurrence of two terms in a row (or any other issue)… Not sure 
if there is any easy way to implement something like this (but a line ending 
with a dot should be a good heuristic, no?)
