Why must variable names begin with $? I can't see any
real reason, except when signalling a replacement within
a string (e.g., "... $var ..."). The language would be less
cumbersome if the dollar was optional otherwise.

Two letters: HA
But to answer your question based on current PHP, non-prefixed variables
would conflict with define()d constants, which appear as: $foo =
'abc'.bar;

Why do you say this? I prefer "foo $bar blah".

Ok, that's interesting but irrelevant for most of my code. Readability
is a higher priority in most cases.
Thanks for pointing this out,

If you use a compiler cache like apc, this performance hit will be
totally removed as the optimizer compiles both representations into the
same format.
