Multiple assignment count mismatch

[benjis]

According to: https://crystal-lang.org/docs/syntax_and_semantics/multiple_assignment.html

If the left-hand side contains just one variable, the right-hand side is considered an array:
names = "John", "Peter", "Jack"

The above is the same as:

names = ["John", "Peter", "Jack"]

However, above code throws "Multiple assignment count mismatch" syntax error.

➜  ~ crystal test.cr
Syntax error in test.cr:1: Multiple assignment count mismatch

names = "John", "Peter", "Jack"
^

Is this intended behaviour in Crystal or the doc needs a update?

• Crystal 0.24.1 (2018-01-27)
• LLVM: 5.0.1
• Default target: x86_64-apple-macosx

It looks as though the spec doesn't allow for this behavior, suspect the docs are wrong at this point

crystal/spec/compiler/parser/parser_spec.cr

Line 145 in 322d1c4

assert_syntax_error "a = 1, 2, 3", "Multiple assignment count mismatch"

Bare array creation was removed in 0.24.0 (see #4824). The language reference has not yet been updated.
