I'm modifying a program which uses IPC::Open3::open3 to fire up mysql and query the database. What I don't understand is when they write to the "filehandle" created they put curly braces around the whole variable name like this: 
print {$write_fh} "$database_query";

I know ${write_fh} would simply be a way to be explicit about the variable name, but I do not know what it means to put the whole name in curly braces like {$write_fh}. What does that indicate? Any input would be greatly appreciated!
