----------------------------------------
Bug #12031: Make ERB work with --enable-frozen-string-literal
https://bugs.ruby-lang.org/issues/12031

* Author: Jeremy Evans
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.4.0dev (2016-01-26) [i386-openbsd]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
ERB currently does not work with --enable-frozen-string-literal:

~~~
$ echo "a" | RUBYOPT=--enable-frozen-string-literal erb
-:1:in `concat': can't modify frozen String (RuntimeError)
        from -:1:in `<main>'
        from /usr/local/lib/ruby/2.3/erb.rb:864:in `eval'
        from /usr/local/lib/ruby/2.3/erb.rb:864:in `result'
        from /usr/local/lib/ruby/2.3/erb.rb:846:in `run'
        from /usr/local/bin/erb23:149:in `run'
        from /usr/local/bin/erb23:170:in `<main>'
~~~

The attached patch makes it work with --enable-frozen-string-literal:

~~~
$ echo "a" | RUBYOPT=--enable-frozen-string-literal RUBYLIB=~/ruby/lib erb
a
~~~
