Bug #6347: Syntax error on calling method with symbol without space and parens in else clause

• Status: Closed
• Assignee: matz (Yukihiro Matsumoto)
• Target version: 2.0.0
• ruby -v: ruby 2.0.0dev (2012-04-23 trunk 35432) [i386-mswin32_100]

　ささだです．

　次のようにすると syntax error になるんですが，これはこういうもんでしょうか．

if 1==2
else
p:foo
end

#=>

ruby 2.0.0dev (2012-04-23 trunk 35432) [i386-mswin32_100]
test.rb:3: syntax error, unexpected tLABEL
p:foo

バグであることが確実な気がするもの。(1.8ではp(:foo)と解釈されるもの)

if true then
p:foo
end

if false
else
p:foo
end

begin
p:foo
end

begin
ensure
p:foo
end

"#{p:foo}"

たぶんバグじゃないかなーと思うもの。(1.8では文法エラーになるが、スペースを入れれば通るもの)

class Foo < p:foo; end

class << p:foo; end

たぶん放置してもいいと思うもの。(元々引数リストをくくる括弧がないと通らないもの)

x = nil, p:foo

true && p:foo

*p:foo
