I find Go really compelling, even though it's not super applicable to my job. When evaluating a new tool, I find I'm weirdly biased to things written in Go.

• I like that it compiles, and have no desire to install someone else's Python
• It just seems to hit the right balance of productivity, performance, simplicity, safety
• The language (and the tech built with the language) just seems built to last

Notes

• Regular Expressions
  • Compile with regexp.MustCompile (no need to check for error)
  • Strings denoted by backticks don't escape; use these for regular expressions
  • For case-insensitive matching, start the expression with (?i)
• Unnamed parameters

Unnamed parameters are perfectly valid. The Parameter declaration from the spec:

ParameterDecl  = [ IdentifierList ] [ "..." ] Type .

As you can see, the IdentifierList (the identifier name or names) is in square brackets, which means it's optional. Only the Type is required.

The reason for this is because the names are not really important for someone calling a method or a function. What matters is the types of the parameters and their order. This is detailed in this answer: Getting method parameter names in Golang

• Named result parameters
