Missing information on GC assist

In  without looking at the stack trace, the transition to `inactive` is confusing. It is actually caused by ``` M=1925740 P=12 G=55 StateTransition Time=375984530827392 Resource=Goroutine(55) Reason="GC mark assist wait...

`info` command doesn't have custom tab completion

1

When typing `info is_emp`, it completes to `info is_empty(`, including the trailing opening parenthesis. More generally, `info ` offers the same 856 candidates that `` on an empty line would.

`info` doesn't know about dimensions

A command like `info CurrentDensity` fails with `Not found`. I would expect at least output similar to that for units: a basic description, whether the dimension is derived or not,...

For example, ``` x := 159.9999313354492045391452847979962825775146484375 y := 159.99993133544920453914528479799628257751464843749 ``` and ``` x := 159.99993133544922 y := 159.9999313354492 ``` are the same. As usual, floating point numbers are crazy and...

SA4015: more wrong float math

2

Seen this original code in the wild: `int(math.Ceil(float64(gap / 2)))` (for var gap int) – staticcheck pointed out that the call to math.Ceil was pointless, so the code got changed...

Subpar trees for unclosed blocks

For the following snippet ``` package pkg func foo() { // bar ``` the grammar produces an `ERROR` (not a `MISSING "}"), and places the `comment` node outside the `function_declaration`:...
