Comment:
@ppurka: `log`, like `exp`, never had an "INPUT" description; the `hold`
parameter is introduced informally in both cases; please open a separate
ticket.
@kcrisman: `log?` is fine, and identical to `ln?`
Reviewer's patch addresses this patchbot failure:
{{{
File "src/sage/ext/fast_callable.pyx", line 1524, in
sage.ext.fast_callable._expression_binop_helper.get_builtin_functions
Failed example:
sorted(list(builtins.values()))
Expected:
['abs', 'abs', 'acos', 'acosh', 'add', 'asin', 'asinh', 'atan',
'atanh', 'ceil', 'cos', 'cosh', 'cot', 'csc', 'div', 'exp', 'floor',
'floordiv', 'inv', 'log', 'log', 'mul', 'neg', 'pow', 'sec', 'sin',
'sinh', 'sqrt', 'sub', 'tan', 'tanh']
Got:
['abs', 'abs', 'acos', 'acosh', 'add', 'asin', 'asinh', 'atan',
'atanh', 'ceil', 'cos', 'cosh', 'cot', 'csc', 'div', 'exp', 'floor',
'floordiv', 'inv', 'log', 'mul', 'neg', 'pow', 'sec', 'sin', 'sinh',
'sqrt', 'sub', 'tan', 'tanh']
}}}
I hazard that this small change won't need another review, so I'll set
positive.
