Not if it's s-expression-based! (laughs in smug lisp weenie)

Or, if the programming language uses infix binary operators:

Not if the programming language has evaluation order from left to right, e.g.

2+3*4

is evaluated as

(2+3)*4.

For example J uses this kind of evaluation.

hyperscript has some operator precedence, but within a given general precedence level you have to explicitly parenthesize if you use different operators:

https://github.com/bigskysoftware/_hyperscript/blob/06f9078a...

https://github.com/bigskysoftware/_hyperscript/blob/06f9078a...

this eliminates most practical precendence questions

NB: one thing that may strike people as strange is that the parse methods are on the parse elements themselves, I like to localize everything about a parse element in one place
