Bug #7615: assignment to context variable changes the precedence order of function call with followed by ' (' (whitespace-bracket)
https://bugs.ruby-lang.org/issues/7615#change-35612

Author: snoble (Steven Noble)
Status: Open
Priority: Normal
Assignee: nobu (Nobuyoshi Nakada)
Category: core
Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2012-12-01 trunk 38126) [x86_64-darwin12.2.0]


this is similar to http://bugs.ruby-lang.org/issues/1801 but it wasn't pointed out then that ruby will use two different parsings at different times

note that in this code `a` and `b` have the same assignment code but are assigned different values
code:
def foo(x); 99; end
a = foo (44) / 11
foo = 99999999
b = foo (44) / 11
puts "a: #{a} b: #{b}" #output of "a: 99 b: 9"

The output of ruby_parser is:
s(:block, 
 s(:defn, :foo, s(:args, :x), s(:lit, 99)) 
 s(:lasgn, :a, s(:call, nil, :foo, s(:call, s(:lit, 44), :/, s(:lit, 11)))), 
 s(:lasgn, :foo, s(:lit, 999999999)), 
 s(:lasgn, :b, s(:call, s(:call, nil, :foo, s(:lit, 44)), :/, s(:lit, 11)))
)

observed in 1.9.4 and 2.0.0-preview2, but does not occur in 1.8.7
