Re: Syntax error in Nested for

[Athanasius]

In the line:

say for keys %$_ for @x;

the second for is being used as a statement modifier on another for loop, but statement modifiers are allowed only on “simple” statements (Statement Modifiers). But you can do this instead:

do { say for keys %$_ } for @x;

Hope that helps,

Ah ! - Thanks - I see it as the very first statement in the docs:

Any simple statement may optionally be followed by a SINGLE modifier,.
