Sort of, you have to delay the compilation though:

irb(main):017:0> begin
irb(main):018:1*     eval "550p"
irb(main):019:1> rescue SyntaxError => e
irb(main):020:1>     puts "Caught a syntax error: " + e
irb(main):021:1> end
Caught a syntax error: (eval):1:in `irb_binding': compile error
(eval):1: syntax error
=> nil
