Whereas I take the opposite approach.  The simple function application is
often a bad function--one that may return bottom--and I'd rather be able to
place hedges around dangerous functions like that.  In contrast, pattern
matching is safe.  Record update (on the third hand) is unsafe, but uses
similar syntax to pattern matching.  It's a mess.  The whole namespace
issue only exists for record access functions, which is a feature that I'd
prefer to have dropped from the language anyways.

Which just goes to show that nobody agrees...
