PaddiM8	7b0435d3ec	Separated parsing into two phases ... The first phase (parser.rs) is generally context-free, and builds a naive AST where for example function calls are parsed as `f*(x)` where `f` is a variable and `(x)`is a group. The second phase (analysis.rs) then creates a new AST, where these are turned into a function call expression instead.	2022-01-14 15:08:19 +01:00
