Parsing error on parsing 'A=1 time'

Parsing error on parsing 'A=1 time'

[Emil Gedda]

$ zsh -c 'A=1 time'
zsh:1: parse error near `time'


Compared to:

$ zsh -c 'A=1; time'
shell  0.00s user 0.01s system 295% cpu 0.003 total
children  0.00s user 0.00s system 0% cpu 0.003 total


This seems to be specific to the time builtin when prepended with a env var
assignment, echo works properly. Could not find a ticket related to this on
sourceforge, my apologies if it has been reported before.

zsh 5.7.1 (x86_64-apple-darwin17.7.0)

Cheers,
Emil

It's a little obscure, but this isn't actually a bug.  If you look in
the appropriate manual section, you'll see that "time" is defined as a
"complex command" which takes a pipeline as an argument.  So assignments
etc. come after it (and potentially a number of "|"s with their own
command lines that may include assignemnets).

To put it another way, the parse error here is roughly similar to the
failure you get here:

A=1 { echo; }

In both cases, no command line can appear before the complex command.
