print $fh LIST;
and
print { $fh } LIST;
are equivalent.

The curlies are required when dealing with more complex expressions for the file handle. 

>perl -e"my @h = ( \*STDOUT ); print $h[$_] qq{foo!\n} for 0..$#h"
syntax error at -e line 1, near "] qq{foo!\n}"
Execution of -e aborted due to compilation errors.

>perl -e"my @h = ( \*STDOUT ); print { $h[$_] } qq{foo!\n} for 0..$#h"
foo!
