Re^3: How to read in large files

And this nuance occurs because:

In the case of foreach ( EXPRESSION ) { BLOCK }, the EXPRESSION is evaluated in list context. The <FILEHANDLE> operator returns a list of records from the file when evaluated in list context. Logical records are typically based on lines within the file.
In the case of while ( EXPRESSION ) { BLOCK }, the EXPRESSION is evaluated in scalar context for its Boolean value. The <FILEHANDLE> (diamond) operator returns a single record from the file when evaluated in scalar context.

Thanks all. I was unaware foreach was different from while other than syntactically.	[reply]
