<& equivalent for Es

[cattokomo]

Is there any equivalent for <& in Es? While >& have something similar which is >[n=m], <& seems not.

I might be wrong since I read the manpage half-heartedly.

I might be missing something in your question, but <[n=m] is valid syntax (and parses exactly the same as >[n=m], in fact)

; echo {foo >[1=2]}
{%dup 1 2 {foo}}
; echo {foo <[1=2]}
{%dup 1 2 {foo}}

Does the last line of the following example work how you expect?

; echo 'This is some file contents.' > my-file.txt
; cat my-file.txt 
This is some file contents.
; exec {<[3] my-file.txt}
; cat <[0=3]
This is some file contents.

(Note the last line works identically if written as cat >[0=3].)

That's what I wanted, thanks.
