There was a problem hiding this comment.
We don't need the || conditions here, it's already been done in the lines above.

Thanks. One minor nit and otherwise this looks great. |

Fixes #1186
I'm opening this partly just to help identify the problem, my knowledge of the internals of
handlebars.jsis non-existent and there may well be more desirable ways to fix this problem.I believe underlying cause is that the previous
compiler.useBlockParamsis not respected for any subsequent existing programs that are matched. I've just set/stashed/slashed/hacked the value on tochildenvironment, but this is the part that may need to be done differently.Question - how much performance does matching/re-using the existing programs save? (Just curious)
