No, but it didn't take much searching:

"#{if true then 1 end}"

However, syntax highlighting also fails on

3.times { if true then 1 end }

Of these two, the latter is more serious because it affects future end

Adding { to the monster regexp setting off if/unless does not fix
this.  Apparently Vim doesn't like backtracking through the beginning
of a region definition.  I'll investigate a bit more; let me know if
you have any ideas.
