Delimiting Mata code with mata: ... end vs. mata { ... }

[Bert Lloyd]

Dear Matalisters,

When writing Mata code in a do-file, are there important differences between the following two ways of delimiting the Mata content?

Method 1: mata: ... end

mata :
  a
  b
end

Method 2: mata { ... }

mata {
  a
  b
}

Method 2 can be included in loops and Stata programs, are there any downsides?

Thanks,
BL
