You have quotes inside of quotes. Try using different quotes, or using
the q// or qq// operators:
$st = "!--- @{[ get_header('Users') ]} ---!";
$st = qq(!--- @{[ get_header("Users") ]} ---!";
For an explanation of how @{[ ... ]} works...
1. arrays DO get interpolated in strings
2. [ ... ] creates an array reference
3. @{ $array_ref } dereferences an array reference
4. @{[ ... ]} dereferences an array reference built on-the-fly
5. "@{[ ... ]}" expands that array as if it were "@foo"
