If that's true, you should be writing 

print( { $filehandle } $some_data );

Running into problems from omitting those parens is far more likely than running into problem from omitting those curlies. Furthermore, omitting the curlies around the file handle expression when it's needed is likely to result in a compile-time error, whereas omitting parens can fail silently and subtly.

If the argument you posted is valid, then it's far more important for 

print $filehandle $some_data;

to be written as 
print($filehandle $some_data);

[download]
than for it to be written as 
print { $filehandle } $some_data;
