I don't see anything in that file that tracks the session in which the

IIUC, there isn't a command in fish that can be used to compare two strings
to see if one is greater than the other in sorting order. For example, this
doesn't work:
set v1 'foo';
set v2 'bar';
if test $v1 > $v2
...
end
Is there a recommended workaround for this?

I'm working in iTerm2 on a Mac.
Entering "echo $COLUMNS" gives the correct value at most window widths.
However, if the width is less than 20, it always reports 80.

Is is correct to say that in fish all variable values are strings?
For example,
set pi 3.1415928
string length $pi # 9
Is that because the value is actually stored as a string or
does it convert it from a number to a string when "string length" is called
on it?

I was expecting that funced might realize the function was already saved to

a switch on funced to tell it to do that.

But I cannot run it in the background with "myfn &".
Also, if I'm running a long running function, I can't move it to the
