Rakudo's behavior has changed, but it depends on how you invoke it​:

Looks like we get it right in the REPL, but no where else.

From @usev6

Current behaviour​:

$ ./viv -c -e '5.'
===SORRY!===
Decimal point must be followed by digit at (eval) line 1​:
------> 5.⏏<EOL>
Unsupported use of . to concatenate strings; in Perl 6 please use ~ at (eval) line 1 (EOF)​:
------> 5.⏏<EOL>
Parse failed

$ perl6 -e '5. ' ## note the whitespace after the dot
===SORRY!===
Decimal point must be followed by digit
at -e​:1
------> 5.⏏
Unsupported use of . to concatenate strings; in Perl 6 please use ~
at -e​:1
------> 5. ⏏<EOL>

So far so good. There is still a problem when there is no whitespace after the dot​:

$ perl6 -e '5.'
===SORRY!=== Error while compiling -e
Missing semicolon.
at -e​:1
------> 5.⏏<EOL>

Adding a semicolon looks gives one good and and strange error message​:

$ ./perl6-m -e '5.;'
===SORRY!===
Decimal point must be followed by digit
at -e​:1
------> 5.⏏;
Missing semicolon.
at -e​:1
------> 5.⏏;

Turns out it did get it if the error was not at EOF. Fixed that now, turned this into throwing a typed exception, and tested in in S32-exceptions/misc.t.

@jnthn - Status changed from 'open' to 'resolved'
