I merged the PR. Thank you for you patience.

｢testneeded｣

See
https://github.com/rakudo/rakudo/commit/c7a82d451d6506bda9422813fe72974575e473df

You can see some code examples here:
https://github.com/rakudo/rakudo/pull/565#issuecomment-334965048
Maybe these can be turned into tests easily.

As a status update: All code snippet in this ticket die now with 
X::Syntax::Malformed and complain about 'Malformed my' during compilation (I 
think, it was fixed with rakudo commit e1e03e6ed5):

$ perl6-m -e 'my Str where "foo" $test'
===SORRY!=== Error while compiling -e
Malformed my
at -e:1
--> my Str⏏ where "foo" $test

$ perl6-m -e 'my str where "foo" $test'
===SORRY!=== Error while compiling -e
Malformed my
at -e:1
--> my str⏏ where "foo" $test

$ perl6-m -e 'my Int'
===SORRY!=== Error while compiling -e
Malformed my
at -e:1
--> my Int⏏

A while ago I opened a PR (https://github.com/rakudo/rakudo/pull/565) related 
to this ticket. I added some code in order to detect misplaced where clauses, 
etc. But that PR was not merged (probably my patch was a bit over-engineered). 
It looks like my branch is not mergeable anymore -- maybe I should close it.

Code:
my Str where 'foo' $test;

Result:
===SORRY!===
Type 'Str' is not declared. Did you mean 'str'?
at ./test.pl:2
--> my Str ⏏where 'foo' $test;
Malformed my
at ./test.pl:2
--> my Str ⏏where 'foo' $test;


Well, let's also try what it says:
my str where 'foo' $test;

Result:
===SORRY!===
Type 'str' is not declared. Did you mean 'Str'?
at ./test.pl:2
--> my str ⏏where 'foo' $test;
Malformed my
at ./test.pl:2
--> my str ⏏where 'foo' $test;


Current error message is misleading. But when it's fixed, maybe it could
figure out that 'where' is misplaced? For me it was a natural thing to type
“Str where 'foo'”, I think that other people could mistakenly try that too.
If it is possible to detect that and suggest a fix, so much the better.
