Subject: Re: #{} and \" don't like each other

To combine two of my e-mails into one:

1. double-quote as beginning of string literal,
2. string interpolation open,
3. double-quote as beginning of string literal,
4. double-quote as character,

Trying to do 4. by escaping the double-quote renders the double quote 
an end of string literal marker.

The following does not work as intended (the expression is evaluated 
differently than it would be in a variable assignment):

  print "<user #{"name=\"" + name + \""}></user>"

The effect in 4. can be done by enclosing the string literal inside the 
string interpolation in single-quotes.

alternate 3. single-quote as beginning of string literal,
alternate 4. double-quote as character

The following does work as intended:

print "<user #{'name="' + name + '"'}></user>"

5. double-quote as end of string literal,
alternate 5. single-quote as end of string literal,
6. string interpolation close, and
7. double-quote as end of string literal

As to why, I don't know. As to whether it is necessary that it be this 
way, I don't know.

Regards,

Mark
