Function names are case-insensitive (<code>SIN</code> = <code>sin</code>); whitespace
is skipped between tokens. The <code>'/' '[' expr ']'</code> tail captures the
dual-bracket form Fanuc uses for <code>ATAN[a]/[b]</code>; non-ATAN callers that
happen to use it produce a function with an extra arg, which the evaluator
rejects with an arity error.
Function names and keyword operators (<code>MOD</code>, <code>EQ NE GT GE LT LE</code>,
<code>AND OR XOR</code>) are case-insensitive (<code>SIN</code> = <code>sin</code>,
<code>EQ</code> = <code>eq</code>); each keyword requires a non-identifier character
on its right boundary so <code>EQ1</code> is not the <code>EQ</code> operator
followed by <code>1</code>. Whitespace is skipped between tokens. The
<code>'/' '[' expr ']'</code> tail captures the dual-bracket form Fanuc uses
for <code>ATAN[a]/[b]</code>; non-ATAN callers that happen to use it produce a
function with an extra arg, which the evaluator rejects with an arity
error.

Operator precedence intentionally puts boolean / logical layers below

matching the Fanuc Custom Macro B spec for <code>IF [..] GOTO</code> /
