Inline adding for a struct member's RHS generates an error because it parses to 2 results

[harrisont]

Repro:

.MyVar = [
    .A = 1 + 1
]

Error message:

Should parse to exactly 1 result, but parsed to 2

[harrisont]

More minimal repro:

.MyVar=[.A=1 +1]

but removing the whitespace makes the error go away:

.MyVar=[.A=1+1]

[harrisont]

The parse looks to be ambiguous because it can't tell if it's one statement (.A=1 +1) or two (.A=1, +1).
For non-struct statements this is solved by requiring a newline between the statements, but structs allow declaring more than one member on the same line, only separated by whitespace.
