Use different regex engine for different use cases/plugins

Question

By default re=0, however I'm running into those issues:

• re=1 makes ctrlp.vim much faster
• re=2 makes vim-jsx-pretty much faster

And somehow re=0 can't seem to get those right for me.

Is there a way to set different re values for different plugins w/o having to fork anything (I understand \%#=0, \%#=1, \%#=2 could be used to force a particular engine in a particular place, see :help two-engines).

Edit: vim-jsx-pretty isn't the issue, thank to :syntime on I can see:

  TOTAL      COUNT  MATCH   SLOWEST     AVERAGE   NAME               PATTERN
  1.995582   11     0       1.995576    0.181417  typescriptArrowFuncDef (\(\_s*[a-zA-Z\$_\[.]\_[^)]*\)*)\s*=>

Which comes from Vim itself.

Edit 2: removing https://github.com/leafgarland/typescript-vim did fix perf issues.
