} Is there a built-in way to repeat an argument N times?
Not really. You have to admit it's a rather unusual thing to do. It
can be done by abusing other expansions, as you've discovered.
} It'd be nice if I could write (something like):
}
} upload-files file1(N3) file2(N10) file3(N4)
You can create an array of N empty elements just by assigning to the
Nth position:
N[100]=()
And then:
upload-files file1$^N[1,3] file2$^N[1,10] file3$^N[1,4]
Works up to however much memory you're willing to waste on allocating
empty array slots.
There are other ways, e.g.
upload-files file2${^${:-{1..10}}/*/}
upload-files file2(e{'repeat 10 reply+=($REPLY)'})
though the latter requires "file2" to actually exist, which sometimes
might be a good thing.
