Hi.
I get the following error from the following statement :

Something is broken. Does anyone know whats going on with this ?

This is because when interpolating global variabl= es in a string, you're allowed to omit the curly braces.

The following are equivalent:

$ irb
&g= t; $greeting =3D "Hello"
> puts "#$greeting= world."
Hello world
> puts "#{$gr= eeting} world."

Hello world

So, you're string "#$&quo= t; makes ruby think you're about to interpolate a global variable. Howe= ver, you then fail to provide the name of a global.

=C2=A0

s=3D"#"+"$" and s=3D"#\$" work ok, but that d= oes not help when the
string occurs in data which goes into eval.

Also, this is not good
irb(main):008:0> s=3D("xxxxxx.....#$yyyyyyyyy")
=3D> "xxxxxx....."

Is there a fundamental problem with the Ruby parser ?
or is this just an isolated glitch ?
