I think it would make more sense for anything that isn’t an “lvalue” to be an error. So:

sin(0)+1 = 1   ;# error
sin(0) = 1 ;# OK
sin = 1 ;# OK

And maybe:

“sin(0)+1” = 1 ;# OK
“sin”(0) = 1 ;# OK

That is the LHS can be:

1. a bareword.
2. a bareword followed by a parenthesized expression.
3. and possibly a quoted string possibly followed by a parenthesized expression.

Probably {...} and “...” should be legitimate quotes.
