Question

I was wondering if it was possible to call a function inside a Perl here doc

sub Function
{
}

print<<HERE;

  Function()

HERE

Answer 1

Do you mean that you want the function’s return value to be interpolated into the heredoc?

sub Function {
    qw( Hello, World! );
}

print <<HERE;

  @{[ Function() ]}

HERE

To explain the syntax, perlmonks says:

The @{} interpolates an array into your here-doc, and the inner [] creates an anonymous array, whose elements consist of whatever expression(s) you want to put between them.
