Bug #8140

Incorrect warning: `+' after local variable is interpreted as binary operator

Added by Glyn Normington about 1 year ago.

Status:Open
Priority:Low
Assignee:Yukihiro Matsumoto

ruby -v:ruby 1.9.3p374 (2013-01-15 revision 38858) [x86_64-darwin12.2.1] Backport:

Description

The statement:

puts '' +''

generates an invalid warning when executed with "ruby -w" which (a) implies a syntactical ambiguity where there is none, and (b) refers to a "local variable" of which there are none.

Note that:

puts ''+''

and:

puts '' + ''

produce no warnings.
