I second that. My favorite implementation of this is in Tcl, where curly 
braces {} mean that the text they enclose is unmodified. Since language 
constructs using them are normally balanced this is not an impediment.

One extremely useful application of this (aside from long strings) is 
specifying inline data frames - I don't know how to do this otherwise.

I.e. something like:

A<- scan.string({#
Id Value Mark
1	a	3
2	b	4
#	})

                          best
