The man thinks..

• Don’t reinvent basic data-types (unless performance is a concern).
• Don’t avoid standard libraries just because they are portable.
• Be wary of using multiple libraries with overlapping functionality.
• To the extent where it’s possible, keep library usage as a private implementation detail.
• Use the right tool for the right job - don’t waste time on religious discussions.
