Description
Just an interesting thing that I found. It seems that continuously adding '{' doubles execution time with each '{' and also consumes 100% CPU while running. Not sure if this should be treated as a bug or not.
Long backtrace of running {{{{{{{{{{{{{{{{{{ (thats 18 '{'):

Research direction
Reproduce the reported slowdown with the 18-character {{{{{{{{{{{{{{{{{{ input and review the linked backtrace gist first. Trace where repeated { characters are processed and verify that execution no longer grows exponentially or consumes 100% CPU.
