I have read a number of posts on the use of eval() in Javascript, and I
agree that its use is questionable. But it does beg the following
question:
"How arbitrary does a string need to be before the use of eval() is
required to execute it?"
Given the following code, I'm able to evaluate/execute most expressions
like: "a.b.c.d()"

Hi -
I'm trying to subclass a dict which is used as the globals environment of
an eval expression. For instance:
class Foo(dict):
def __init__(self):
self.update(globals())
self = 42

For some odd reason, I am trying to do some complex time calculations
that I want to let the user define. So I set up a table with
EventID EventType EventExpression
1 SolarNoon datediff("n",Sunrise,Sunset)
etc.
This is supposed to be evaluated with
TimeofNoon=Eval(EventExpression)

This question was asked in comp.lang.javascript with no result.
In IE5.x and IE6, I want to display an image when the user rolls over a
text link. The image does indeed display, but only on the first
rollover. It seems that the image height and width become set to zero
after the image is displayed once; or perhaps that the
height:expression(eval(...)); code is executed only once for each page
load/reload.

FAQ Topic - When should I use eval?
-----------------------------------------------------------------------
The ` eval() ` function should _only_ be used when it is necessary to
evaluate a string supplied or composed at run-time; the string
can be anything from a simple (but unpredictable) expression such
as 12*2.54 to a substantial piece of javascript code.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
