The $find() function returns true if the sequence contains the specified
value. The $find_index() function returns the index of the first element
in the sequence that is equal to the specified value or $size(<sequence>)
if none is found. For string sequences, it's possible to request case-
insensitive comparison with a flag.

It returns the list of uint64 integers starting from <begin> (including)
to <end> (excluding) with the specified <step> or 1 if unspecified. For
example:
hdr = foo.hxx bar.hxx baz.hxx
src = foo.cxx bar.cxx baz.cxx
assert ($size($hdr) == $size($src)) "hdr and src expected to be parallel"
for i: $integer_sequence(0, $size($hdr))
{
h = ($hdr[$i])
s = ($src[$i])
...
}

Specifically, now we can do:
x = [uint64] 0x0000ffff
cxx.poptions += "-DOFFSET=$x" # -DOFFSET=65535
cxx.poptions += "-DOFFSET=$string($x, 16)" # -DOFFSET=0xffff
cxx.poptions += "-DOFFSET=$string($x, 16, 8)" # -DOFFSET=0x0000ffff
Note that there is no hex notation support for the int64 (signed) type.

Available overloads:
$sort(<names> [, <flags>])
$sort(<ints> [, <flags>])
$sort(<strings> [, <flags>])
$sort(<paths> [, <flags>])
$sort(<dir_paths> [, <flags>])
The following flag is supported by the all overloads:
dedup - in addition to sorting also remove duplicates
Additionally, the strings overload also support the following flag:
icase - sort ignoring case
Note that on case-insensitive filesystem the paths and dir_paths overload's
order is case-insensitive.

This can be useful if we want to pass a value on the command line, for
example, in a testscript:
$* config.cxx=$quote($recall($cxx.path) $cxx.mode, true)

All non-const global state is now in class context and we can now have
multiple independent builds going on at the same time.
