Yes, I want to keep the result. And no, I don't really need to
display this result, at least in the "raw" form - the "echom" in
my simple example is just for convenience of testing. My real
goal is not to just print the message, but rather to post-process
it using existing set of VIML functions. Just to mention several
examples, some of those VIML functions are filling location list
of the current window with entries, extracted from the string,
returned by TestStringIf(). TestStringIf() is also invoked from
'completefunc' to get the information for the user-defined code
completion.
Generally speaking, TestStringIf() acts as a "protocol
implementation" for existing library of VIML functions.
So, my TestStringIf() must somehow takeover the string from the
ruby string variable and make it available in the VIML string
variable. What I don't like in my existing solution, that there
is potentially expensive processing of the string - decorate /
parse (I mean "decorate" is gsub(), "parse" is VIM::command("let
...")). Are there any way to avoid this "overhead" ? Something
like "raw assign VIML variable from the ruby variable" ?

This I have already studied - ":help ruby" drops me on the same
page as ":help if_ruby.txt". Are there any other documents /
howto's for vim ruby integration ?
